Not a goods classification. · deterministic IBAN ValidationValidates an IBAN from any of 70+ countries: checksum, country length and in-country account structure, and resolves the bank and branch codes. · deterministic Phone Number ValidationValidates and normalises a phone number to E.164, classifies the line type, and resolves the province for Turkish landlines. · deterministic Tracking Number IdentificationIdentifies which carrier a tracking number belongs to, validates it where a checksum exists, and returns the canonical tracking link. · deterministic Turkish Address ParserSplits a free-form Turkish address into neighbourhood, street, building, floor, flat, district, province and postcode. · deterministic Turkish ID & Number ValidationValidates Turkish national ID, tax number, IBAN, licence plate, IMEI, barcodes, KEP, MERSİS, postal code and ISBN from one endpoint, with type auto-detection. · deterministic Build Turkish IBANBuilds a Turkish IBAN from a 5-digit bank code and account number, computing ISO 7064 check digits. · deterministic EPC QR PayloadBuilds an EPC069-12 v3.1 V2 (002) SCT payload.

Country is required. · deterministic Turkish Business DaysAdds business days or counts them between two dates, accounting for Turkish public and religious holidays including half-day eves. · deterministic Turkish e-Invoice (UBL-TR) ParserTurns a UBL-TR e-Invoice or e-Archive XML document into clean JSON: parties, line items, taxes and totals. · deterministic Turkish FAST / TR Karekod PayloadBuilds a person-to-person TR Karekod (FAST) payment payload from IBAN, name and optional TRY amount. Text only — no PNG. · deterministic Turkish Postal CodeValidates a 5-digit Turkish postal code and resolves the province from the first two digits (plate map). · deterministic Turkish Service-of-Process ClockComputes the deemed-received date and the HMK deadline (with holiday shifting) for a Turkish notification, from the date the underlying event actually happened. · deterministic Turkish Severance, Notice & LeaveComputes Turkish severance (kıdem), notice (ihbar) and annual-leave entitlement from service dates and the gross wage, using the official ceiling and minimum-wage tables for the given day. · deterministic
