Web bulk validation
Paste a working list into the authenticated bulk tool and review structural results without uploading a permanent customer file.
Bulk validation for South African teams
Validate lists of SA ID numbers without building a privacy liability
Check format, date encoding, citizenship indicator, and Luhn checksum through the web bulk tool or REST API. CheckID processes each request in memory and stores no ID number or decoded validation result.
Choose the workflow that fits
Bulk validation API
Send a batch from your server and receive predictable JSON for each item. Keep API keys and raw ID numbers out of client-side code and logs.
Single validation API
Use the R99 API Starter plan for up to 1,000 single calls per month when batching and team access are not required.
