    How batch matching strengthens compliance and operations

    Faster Year-End Processing

    Process thousands of vendor and contractor records in hours. Batch TIN Matching removes the manual verification bottleneck, letting finance and accounts payable teams get 1099 forms and compliance reports out on time, without the year-end scramble.

    Reduce Compliance Risk

    Validated TINs mean dramatically lower exposure to IRS penalties, B-Notices, and rejected filings. Every record in your batch is checked to confirm business name and tax ID combinations before anything is submitted to regulators.

    Clean, Enriched Outputs

    Get more than a match. When you request appending, batch results can include current address and NCOA updates. Your data is returned in a clean, structured file ready for reporting or year-end filing, cutting hours of manual cleanup.

    72-Hour Or Less Turnaround

    Most batches are returned in less than 72 hours.

    Any File Size

    Upload anything from a short vendor list to an enterprise-scale dataset. There's no practical file size limit, and the system processes multiple batches in parallel without sacrificing speed or accuracy.

    20M+ Verified Records

    Every record is returned in a clean, structured file format with clearly labeled match results, allowing your team to review, sort, and act on data immediately without additional processing.

    Batch TIN Matching is designed for organizations of all sizes that manage vendor, payee, or customer data. Accounts payable teams use it to support accurate year-end 1099 preparation, while tax professionals rely on it to validate client vendor records prior to filing. Financial institutions and compliance teams use batch validation and sanctions screening to support Know Your Business (KYB) reviews, vendor onboarding, and ongoing compliance monitoring at scale.

    EIN Lookup is designed to help you quickly find business information and locate an EIN for a business. It’s ideal when you need information on an individual vendor, customer, or business. If you’re submitting a batch file and some records are missing EINs, we can also use our EIN Lookup database to append available EINs before validating your file.

     

    Batch TIN Matching is designed for validating large volumes of business records. Simply submit your vendor or customer file, and we’ll validate each business name and Taxpayer Identification Number (TIN) against IRS records. Once processing is complete, you’ll receive a detailed analysis of the results and can choose to receive the validated and corrected file.

    Batch TIN Matching is not included in standard subscriptions, as it is a service tailored to each organization’s specific requirements. Pricing is based on factors such as file volume, turnaround time, and any requested customizations or data enrichment. A complimentary initial batch analysis is available, and most projects are completed within 72 hours or less.
