Validate your entire vendor population in a single pass
Q4 pre-filing cleanup. Post-migration validation. Vendor master remediation. M&A due diligence. Every one of these needs a full population run through IRS TIN matching and sanctions screening — fast, consistently, with output organized for action. Upload once, run every validation you need, and get back a categorized exception report with outreach ready to launch.
Excel or CSV straight from your ERP export. No reformatting.
Full access on every plan. Uploads are priced per file — see pricing.
The problems in a vendor master are invisible until you run all of it
Vendor populations accumulate data quality problems over time — ERP migrations that truncated legal names, sole proprietors who submitted DBAs, entities that restructured and never sent an updated W-9, records onboarded before a validation program existed. None of these show up in normal AP operations. All of them produce CP2100 notices after the 1099 is filed.
Manual review doesn't scale
Checking thousands of records one at a time before a January deadline isn't operationally viable. Bulk runs the full population and returns results ready to work.
Unvalidated records are open risk
Every unvalidated record in a 1099-reportable population is potential CP2100 exposure. Bulk validation converts unknown risk into a finite exception list with time to resolve it.
Problems compound
A master that's never been systematically validated gains errors with every onboarding event. One pass surfaces all of it — mismatches, invalid TINs, missing W-9s — in a single categorized report.
Sampling isn't a program
Spot-checking isn't a defensible compliance posture. Bulk enforces consistent validation across every record, so the documentation shows full coverage rather than a sample.
Upload to remediation in five steps
Upload your file
Excel, CSV, TSV, or pipe/semicolon delimited — straight from your ERP export. No reformatting. Duplicate records are detected automatically before processing runs.
Select validations
Choose one or more types — TIN matching, sanctions screening, EIN lookup, address validation, GIIN, LEI. All selected validations run in a single pass.
Automated processing
Every record is processed — formatting issues flagged, selected validations run, results categorized by type and severity.
Review the exception report
Results come back per record with specific result codes — not just pass/fail. Mismatches, invalid TINs, missing W-9s, and sanctions hits are categorized separately so the team can prioritize.
Export & remediate
Download structured output for vendor master updates, trigger automated W-9 correction outreach across the whole exception population, and retain the processing record for audit.
Lockout protection built in
The IRS locks accounts for 96 hours on duplicate submissions — including accidental ones from overlapping batch jobs. Duplicate detection runs before anything reaches the IRS, so a routine mistake doesn't cost you four days mid-campaign.
Six validation types, any combination, one upload
Results are returned per record for each selected type — so one pass answers every question you have about a vendor rather than requiring a separate run for each.
IRS TIN Matching
Validate name/TIN combinations against official IRS records. Returns specific result codes — name mismatch, invalid TIN, TIN type — not just pass/fail.
Sanctions Screening
Screen every record against 330+ global watchlists — OFAC, FinCEN, BIS, EU, UN and more — with fuzzy matching and alias detection in the same pass.
EIN Lookup
Cross-reference company names and EINs against the entity database — identify name/EIN mismatches and surface the correct entity information for correction outreach.
Address Validation
Validate and standardize mailing addresses via USPS — confirming deliverability before B-Notice outreach and correction campaigns go out.
GIIN Validation
Validate Global Intermediary Identification Numbers for foreign financial institution compliance and FATCA reporting workflows.
LEI Validation
Validate Legal Entity Identifiers for financial counterparty identification and regulatory reporting requirements.

master extract with no reformatting.
Delimited — .csv, .tsv, .txt with tab,
pipe, or semicolon delimiters. Most AP systems export one of these natively.
Six moments worth running the whole population
Q4 pre-filing
Run in October, not December. The full 1099-reportable population validated in one pass gives your team eight to ten weeks to resolve exceptions before the January deadline.
Post-ERP migration
Migrations routinely truncate legal names, reformat TINs, and introduce errors at scale. Validate the migrated master before the first filing on the new system.
M&A due diligence
Validate the acquired entity's vendor population before the first consolidated filing — surfacing TIN problems and sanctions exposure before they become your liability.
Vendor master cleanup
For masters never systematically validated — run everything, categorize the exception report by issue type, and work corrections before they accumulate further.
Periodic re-screening
Sanctions lists update continuously. Re-screen the active vendor population quarterly to catch new designations on existing relationships before the next payment run.
CP2100 response
Upload the mismatch population to assess current status — some will already be fixed — then launch automated B-Notice outreach for the rest in a single operation.
Questions about bulk validation
What file formats can I upload?
Excel (.xlsx) and delimited files (.csv, .tsv,
.txt) including tab, pipe, and semicolon delimited. Most ERP and AP systems export
natively in one of these, so no reformatting is needed before upload.
How many records can I process at once?
There's no practical per-file record limit — files in the hundreds of thousands of rows are processed routinely.
Duplicate records are detected automatically before processing starts, which also prevents the duplicate submissions that trigger 96-hour IRS account lockouts.
Can I run more than one validation on the same upload?
Yes — any combination of TIN matching, sanctions screening, EIN lookup, address validation, GIIN, and LEI. All selected validations run against the file in a single pass, with results returned per record for each type.
When should I run a bulk validation before filing season?
October, not December. An October run leaves eight to ten weeks to work the exception report, send corrected W-9 requests, and revalidate before the January deadline.
A December run tells you exactly how big your problem is with no time left to fix it.
What does the output look like?
A structured export with results per record and specific result codes rather than a pass/fail flag. Mismatches, invalid TINs, missing W-9s, and sanctions hits are categorized separately so the team can prioritize — and automated W-9 correction outreach can be launched for the entire exception population at once.
Can this help me respond to a CP2100 notice?
Yes. Upload the mismatch population from the notice and run bulk TIN matching to establish current status — some records will have been corrected since filing. Then launch automated B-Notice outreach for the remainder in one operation, with every send logged for the abatement record.
The free CP2100 B-Notice Triage tool is a good first step if you're working a notice right now.
