Identity tools generate and validate IDs you paste from tickets, spreadsheets, or device logs. Recent batches added telecom and supply-chain format checks, UUID validation, and GS1-style product identifiers—all local, with no registry lookup unless a page says otherwise.
Generate and validate core IDs
- Open the Identity hub for UUID v4/v7, ULID, Nano ID, and MongoDB ObjectId in one place.
- UUID validator — bulk-check version and variant bits on pasted GUID lists.
- E.164 phone normalize — strip formatting and validate ITU-style lengths.
Telecom and device identifiers
- IMSI format check, MEI format check, and RTAC format check — digit shape for mobile subscriber and equipment ids.
- ICCID checker, IMEI checker, and MEID checker — SIM and handset checksum pages (also listed under Protocol).
- MMSI validator — maritime mobile service identity rules.
Product, location, and government codes
- GTIN check, UPC-A checker, and EAN-13 checker — retail barcode checksums.
- GLN format check, SSCC check, and ASIN format check — logistics and marketplace identifiers.
- NSN format check, CAGE code format, and NHS number check — defense and public-sector id shapes.
Financial, media, and securities ids
- ISBN validate, ISSN validator, and ISRC validator — publishing and recording codes.
- ISIN validate, CUSIP checksum, SEDOL checksum, and FIGI format — securities identifiers without market data lookup.
- LEI check, DUNS check, and SWIFT/BIC validator — entity and banking id layout checks.
