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.

Use the R99 Solo + API plan for up to 1,000 single calls per month when batching and team access are not required.
