IMEI Code Validator

IMEI validation is a focused tool for verifying the structural integrity of IMEI numbers and surfacing origin hints where TAC data is available. It accepts a 15-digit input, normalizes common separators, and applies the standard Luhn checksum. Results include a normalized IMEI, a validity flag, and a TAC-based attribution if present.
Conceptually, the tool separates data quality checks from identity inference. The normalization step removes spaces, hyphens, and dots to produce a canonical 15-digit string. The checksum step ensures the last digit matches the Luhn calculation. The optional TAC lookup maps the first eight digits to potential manufacturers and issuing regions using a local map that can be updated over time.
Who benefits include device manufacturers validating batch records, telecom operators verifying device eligibility, QA teams auditing activation flows, and risk teams performing device identity checks. The unique value lies in combining strict format validation with optional origin hints, enabling rapid triage of suspicious entries and cleaner provisioning logs. The core features are fast, deterministic validation, optional TAC-based enrichment, and structured outputs suitable for automation and auditing.
Use cases span onboarding new devices, validating scanned assets during inventory, and pre-activation checks in service workflows. The tool is designed for offline or edge deployments where network access is limited, and it can be extended to support additional TAC datasets or export formats without changing the core validation logic.
