Finding Accuracy Gaps in Your Skip Tracing Workflow
Pinpointing where accuracy issues arise in your skip tracing workflow is crucial. These problems can crop up at various stages – from the initial data source to the final contact attempt. The first step is identifying these weak points. Then, dive deeper into specific challenges that compromise accuracy before conducting a full audit of your process.
Common Workflow Problems
One of the biggest culprits in skip tracing inaccuracies is stale contact data. When databases aren’t updated frequently, you’re left with outdated information. Phone numbers get reassigned, people move, and properties change hands. This outdated data leads to wrong-party contacts, disconnected numbers, and undeliverable mail, wasting both time and resources.
Another common issue is inconsistent address formatting, which causes matching failures. Variations in address formats – like missing unit numbers, unconventional abbreviations, or incomplete ZIP+4 codes – can lead to duplicate records, misdirected mail, and failed API matches. These inconsistencies waste effort and money.
Unverified phone numbers are another accuracy roadblock. Without proper verification, agents often call numbers that are disconnected, recycled, or simply incorrect. This not only wastes time but can also lead to compliance risks under U.S. communication laws if wrong numbers are repeatedly dialed.
Then there’s the problem of manual processing errors. Mistakes like transposed digits, swapped names, or copy-paste errors can derail searches entirely. Even small errors can snowball when working with thousands of records, driving up costs and frustrating your team.
Lastly, the lack of validation processes compounds all these issues. Without proper checks, inaccurate or unverified data flows unchecked through your workflow, creating a ripple effect of errors.
Recognizing these pitfalls is a critical step toward improving your process.
How to Audit Your Skip Tracing Process
A thorough audit can uncover exactly where accuracy breaks down. Begin by mapping your entire workflow from start to finish. Document every step: how data enters your system, how it’s enriched and validated, and how it moves between teams. Include all data sources, tools, and handoff points. This map will serve as your diagnostic tool.
Next, evaluate each data source and enrichment step. For every source – whether it’s your CRM, public records, or third-party services – ask key questions: How often is the data updated? What areas does it cover? Are there accuracy metrics or match scores provided? Does it conflict with other trusted sources? Can it integrate with APIs for real-time updates? If you don’t have answers, you’ve found a gap.
Benchmark your performance metrics at each stage. Measure your hit rate (how often you retrieve accurate contact info), right-party contact rate (how often you reach the correct person), and contact-to-resolution time. Break these metrics down by data source and workflow step. If performance drops significantly at a particular stage, that’s where accuracy is slipping.
Trace failed records and analyze team handoffs to locate error sources. Take a sample of failed records and backtrack through the workflow. Was the data outdated? Did a manual error corrupt the record? Did an address formatting issue cause a mismatch? Often, errors occur during transitions between teams or systems. For example, exporting and importing spreadsheets with inconsistent field definitions can create discrepancies. Check whether you’re using a single system of record, whether field names are standardized, and if changes are logged with audit trails.
Leverage APIs for quick diagnostic checks before overhauling your workflow. Run a sample of 500–1,000 records through an enrichment API like BatchData and compare the updated information to your current records. How many phone numbers or addresses changed? How many records now have higher confidence scores? This quick test reveals how much accuracy you’re missing.
Monitor the percentage of accounts requiring rework due to internal mistakes. If agents frequently report data issues or quality-control checks catch many discrepancies, measure how often this happens. Even a small error rate – say, 2% to 5% – can translate to hundreds or thousands of flawed records at scale.
Finally, focus on high-impact fixes. Your audit will likely uncover multiple issues, but not all are equally critical. Prioritize problems that affect the largest number of records, cause the most failures, or pose the greatest compliance risks. Addressing the top three issues will yield far better results than trying to fix everything at once.
Using APIs to Improve Skip Tracing Accuracy
To address accuracy issues in skip tracing, integrating APIs at critical points in your workflow can make a big difference. APIs connect your systems to updated databases, enabling automatic record enrichment, verification, and standardization.
Key API Features for Skip Tracing
When selecting APIs for skip tracing, focus on features that tackle the specific challenges you’ve identified. Here are some essential capabilities to consider:
- Identity resolution: This feature matches individuals across various identifiers like name, address, phone, and email – even with incomplete or inconsistent data. It’s especially useful for piecing together profiles from fragmented records, such as connecting property owners to multiple contact channels.
- Phone verification: Advanced APIs don’t just confirm if a number exists; they identify line type (mobile, landline, or VoIP), carrier details, current status (active, disconnected, or reassigned), and even recent activity. For example, BatchData’s Phone Verification API validates numbers within milliseconds, helping you prioritize dials and avoid wasting time on disconnected lines.
- Address validation and geocoding: These APIs ensure addresses meet USPS standards, correct formatting issues, and add ZIP+4 codes. They can also geocode addresses to latitude and longitude coordinates, which improves match rates and helps verify data across systems.
- Email verification: Verifying email addresses filters out invalid or temporary ones, providing an alternative contact channel when phone outreach doesn’t work.
- Data standardization and normalization: Consistent formatting for names, addresses, and phone numbers – such as E.164 for phone numbers and USPS standards for addresses – improves data reliability and reduces errors during verification.
- Bulk enrichment and batch processing: For teams handling large datasets, bulk APIs can process hundreds or thousands of records in a single job. This is essential for real estate investors or collection agencies managing high volumes of leads. For instance, BatchData’s database includes over 155 million properties, 221 million homeowners, 350 million phone numbers, and 260 million email addresses.
When evaluating API providers, prioritize data coverage (especially for U.S. residential and property data), update frequency, match quality, and multi-channel contact options. Reliable documentation and service-level agreements (SLAs) are also crucial. BatchData stands out with its property and contact data enrichment services, achieving a 76% accuracy rate in reaching property owners.
Building an API-Driven Skip Tracing Workflow
Using APIs effectively doesn’t mean overhauling your entire system. Instead, integrate them strategically into your workflow, such as when new records are added, before outreach campaigns, or when agents flag invalid data.
For example, when a lead enters your CRM, an API call can enrich and verify the contact details immediately. Middleware tools like Zapier or Make (formerly Integromat) can trigger these API calls and update your CRM, keeping your system flexible and adaptable to changing needs.
Here’s how an API-driven workflow might look:
- Data intake: Automatically reject incomplete or malformed records (e.g., missing both name and address) to prevent bad data from entering your system.
- Standardization: Use APIs to clean up and format fields consistently. For example, a name like "JOHN Q SMITH JR" can be standardized to "John Q. Smith Jr." and broken into separate fields. Address APIs can fix formatting issues, expand abbreviations, and add ZIP+4 codes, while phone numbers can be converted to E.164 format (+1-555-123-4567).
- Enrichment: Add missing data and validate existing information. Phone verification APIs confirm if numbers are active and identify line types, while address verification ensures deliverability. Contact enrichment APIs can append additional phone numbers, emails, or addresses to existing records. BatchData’s APIs, for instance, reduce processing time from 30 minutes to just 30 seconds.
- Scoring: Combine data from multiple API responses to create a contactability score. Records with verified mobile numbers, validated addresses, and recent activity signals might receive higher scores, while those with incomplete or unverified data could be deprioritized.
- Outreach: Use the scores to prioritize leads for dialing or mailing campaigns. Agents can access enriched records with multiple contact options, confidence scores, and verification flags directly in the CRM. If a contact attempt fails, trigger another round of API enrichment to refresh the data.
Map API-returned fields into your CRM with clear labels like "Verified Mobile" or "Address Quality" to help agents understand and use the data effectively. Brief training sessions and quick-reference guides can further ensure that your team interprets new fields and scores correctly.
Finally, set up dashboards to monitor API performance and data quality over time. Metrics like right-party contact rates, wrong number percentages, and average attempts per successful contact can help you measure success. If accuracy drops, you can make adjustments – such as refining decision rules or adding data sources – without disrupting daily operations.
To ensure a smooth rollout, start with a small pilot project (e.g., 500–1,000 leads) before scaling up. This allows you to fine-tune your workflow and demonstrate the value of API integration.

Using BatchData APIs for Better Skip Tracing Accuracy
Once you see how APIs can streamline skip tracing workflows, the next step is finding a provider that meets your team’s needs for data coverage, speed, and accuracy. For U.S. real estate teams, BatchData offers a suite of APIs designed to deliver reliable contact information. Let’s break down BatchData’s API capabilities and explore how testing their performance can validate improvements in accuracy.
BatchData’s API Capabilities
BatchData provides three core APIs that tackle common challenges in skip tracing: the Property Search API, the Contact Enrichment + Skip Tracing API, and the Phone Verification API. Together, they form a robust system for locating and verifying contact information.
The Property Search API is the starting point. It retrieves property details and owner information instantly, pulling from a database of over 155 million U.S. properties. For instance, if you’re working with a list of foreclosure addresses, this API can quickly identify the current owner and their mailing address – even if the property was recently sold.
The Contact Enrichment + Skip Tracing API builds on this by adding phone numbers and email addresses. Drawing from a database of 350 million phone numbers and 260 million email addresses, it prioritizes results based on reliability and recency. This automation ensures you get multiple contact options for each record, providing backup channels if your first attempt doesn’t connect. BatchData reports a 76% accuracy rate in reaching property owners, which is significantly higher than many traditional skip tracing methods.
The Phone Verification API adds a layer of quality control. Before making calls, this API checks if a number is active, identifies the line type (mobile, landline, or VoIP), and flags disconnected or high-risk numbers. By filtering out invalid lines and focusing on active mobile numbers, your team can reduce wasted calls and improve the chances of reaching the right person.
BatchData’s approach, described as "One Call Does It All", allows you to retrieve property details, owner information, contact data, and phone verification results in a single API request. This setup minimizes the number of API calls your system needs to make and simplifies integration. The APIs come with clear documentation and easy-to-use endpoints, making it simple to connect them with CRMs, dialers, or custom software.
For teams managing large data volumes, BatchData also offers bulk data delivery. You can upload entire lists – thousands or even tens of thousands of records – and receive enriched, verified contact information in batch files. This is especially useful for large-scale data updates. Plus, the pay-as-you-go model ensures you only pay for the records you process.
Next, let’s look at how to test these APIs to measure their impact.
Running Tests to Measure Results
Testing is essential to prove how these APIs can improve skip tracing accuracy. A controlled test comparing your current process to an API-driven workflow can provide solid evidence of the benefits.
Start by selecting a sample of leads – 500 to 1,000 records that represent your typical data mix and property types. Divide this sample into two groups: a control group that uses your existing skip tracing process, and a test group enriched and verified with BatchData’s APIs. Ensure both groups are comparable in terms of property characteristics, location, and data completeness.
For the test group, follow these steps:
- Use the Property Search API to update owner information.
- Run the records through the Contact Enrichment + Skip Tracing API to append phone numbers and emails.
- Pass all returned phone numbers through the Phone Verification API to flag disconnected or high-risk numbers.
Load both groups into your dialer or outreach system and track their performance separately. Focus on metrics like:
- Match rate: The percentage of records that receive at least one valid phone number or email.
- Right-party contact rate: The percentage of calls or emails that successfully reach the intended person.
- Cost-per-contact: The cost of reaching each contact.
For example, a real estate wholesaler might start with a list of 10,000 property addresses and outdated phone numbers, achieving a 55% match rate and a 12% right-party contact rate using traditional methods. After processing a similar list through BatchData’s APIs, match rates could rise to 70–80%, and right-party contact rates might see a noticeable increase. Even a small improvement – say, from 12% to 15% – could mean hundreds of additional successful contacts per 10,000 dials.
You can also track secondary metrics, like the average number of attempts per successful contact and the percentage of records with no usable contact information. These insights can help refine your workflow and highlight the efficiency gains from using APIs.
Document your findings in a report comparing the control and test groups. Use charts or tables to illustrate metrics like match rate, right-party contact rate, and cost-per-contact. This documentation not only helps justify the investment to stakeholders but also sets a baseline for future improvements. As you tweak API settings, filters, or data sources, running follow-up tests can measure incremental progress.
If the pilot test shows positive results, consider rolling out BatchData’s APIs in phases. Start with high-priority campaigns or portfolios where accuracy is most critical, then gradually expand to other areas as your team gets comfortable with the new workflow. Regularly monitoring these metrics will help you address any issues early and maintain strong performance over time.
Monitoring and Improving API-Driven Skip Tracing
Integrating APIs into your skip tracing workflow is just the beginning. To maintain high accuracy and efficiency, ongoing monitoring and periodic adjustments are necessary. Without a structured approach, even the most well-designed API setup can falter over time, leading to lower match rates and wasted effort.
Tracking Accuracy Metrics
Monitoring key metrics is essential to ensure your APIs perform as expected. A well-designed dashboard can provide visibility into performance and help detect issues early. Some critical metrics to track include:
- Match rate: The percentage of records that return at least one usable contact.
- Right-party contact (RPC) rate: How often those contacts actually connect with the intended person.
- Verified data rate: The proportion of results validated through secondary methods, like phone verification.
- False positive rate: The number of incorrect contacts identified as matches.
- Time-to-contact: The average time between submitting a data request and initiating outreach.
For example, if you notice match rates vary by market segment, this insight can guide better resource allocation or adjustments to your strategy.
To make these metrics actionable, consider adding a dashboard to your CRM or business intelligence tool. Include performance tiles for match rates, RPC rates, and verified data rates, along with trend lines for the past 30, 60, and 90 days. Use conditional formatting to flag metrics that fall below acceptable thresholds. Filters for geography, asset type, and list type can help you dive deeper into specific campaigns or portfolios.
Linking downstream outcomes to API responses is crucial for accurate measurement. Assign a unique ID to every record processed through the API and ensure this ID is carried through all downstream systems, such as dialers, SMS platforms, and direct mail tools. This allows you to calculate RPC and false positive rates, transforming your skip tracing workflow into a fully measurable system.
Set up threshold-based alerts to catch performance issues early. For instance, alerts can notify you if match rates drop significantly, API error codes spike, or wrong-number dispositions increase in a specific segment. If the verified data rate declines, it might indicate problems with verification processes or input data quality. These alerts should include details like the affected API endpoint, region, or campaign, and be routed to both operational and technical teams. Adjust thresholds over time to balance catching critical issues without generating unnecessary alerts.
Once your metrics are in place, the next step is to fine-tune your API settings for even better results.
Adjusting API Parameters
Refining API settings is key to improving performance. Many skip tracing APIs allow you to customize parameters like search strictness, recency filters, and source prioritization.
For example, you can control how many phone numbers are returned per record, their ranking order, or whether to include lower-confidence matches. Tightening name-matching criteria or raising the confidence threshold can reduce false positives, while relaxing recency filters may boost match rates when data is limited.
Testing is essential. Use controlled A/B tests to compare different API configurations. Process a subset of leads with alternate settings while keeping the rest on a baseline configuration. Compare RPC and false positive rates over a fixed period to identify what works best. Document every configuration change so you can quickly reverse ineffective adjustments.
Define clear enrichment rules to determine which attributes make a record "ready" for outreach versus those that are helpful but not essential. For instance, prioritize verified cell phones, deliverable mailing addresses, and recent email activity. Capping the number of phone numbers per record and ranking them by factors like verification status, carrier type, and recency can also improve outcomes.
Regularly review and refine enrichment rules using outcome data. For example, suppressing records with a history of wrong-number dispositions or flagged undeliverable addresses can improve efficiency. Filters for known problem signals can automatically deprioritize low-quality records.
Retry logic and failover strategies can further strengthen your workflow. Differentiate between temporary errors (like timeouts) and hard errors (like invalid input formats). Use retry strategies, such as exponential backoff, for temporary issues. Implement a primary API with secondary providers as backups. If the primary API fails to deliver a match, the request can be passed to a secondary source. When merging results from multiple APIs, apply weighting rules based on historical performance rather than simply combining all available contacts. For instance, if BatchData’s phone verification API consistently performs better for mobile numbers in a specific asset class, prioritize its verified contacts.
Cohort analysis and segmentation can uncover hidden performance trends. Group records by attributes like state, county, or property type to identify areas for improvement. These insights can inform better marketing strategies and improve data quality standards.
Finally, governance practices are essential for maintaining reliability. Document all API endpoints, configurations, and change histories. Limit access to API keys and configuration interfaces based on least-privilege principles. Conduct regular audits – at least quarterly – to ensure enrichment and verification rules are effective, suppression lists are up to date, and accuracy metrics remain within acceptable ranges. Providers like BatchData can assist with data integration and offer advice on best practices to keep your system running smoothly as market conditions change.
