Vad den här ISO-validatorn kontrollerar
De flesta identifierare som företag utbyter varje dag följer en ISO-standard, och de flesta har en kontrollsiffra så att ett felskrivet tecken upptäcks innan det orsakar en misslyckad betalning, en avvisad leverans eller en felaktig post. Verktyget tar det du klistrar in, ett värde per rad, räknar ut vilken standard det kan tillhöra och talar om om det klarar kontrollen, tillsammans med de delar det hittade i värdet.
För datum och tider följer det ISO 8601: kalenderdatum i både kompakt format och format med bindestreck, veckodatum som 2024-W09-4, ordningsdatum, tider med eller utan UTC-offset, varaktigheter som P3Y6M4DT12H30M5S samt intervall. Det känner till skottår, vilka år som har 53 veckor, skrivsättet 24:00 för dygnets slut och skottsekunden, och det pekar ut vanliga misstag: mellanslag i stället för bokstaven T, en blandning av kompakt format och format med bindestreck, eller den 30 februari.
För pengar kontrolleras IBAN mot varje lands register, med exakt längd och nationellt kontoformat, och kontrollsiffrorna verifieras med mod-97. BIC delas upp i bank, land och kontor, ISIN och LEI verifieras med sina egna regler för kontrollsiffror, och betalkortsnummer testas med Luhn-formeln och utgivarprefixet. Valutakoderna kommer från ISO 4217 med numerisk kod och decimaler, och lands- och språkkoderna från ISO 3166-1 och ISO 639, inklusive språktaggar som zh-Hant-TW.
För produkter och logistik valideras ISBN-10 och ISBN-13 (med konvertering mellan dem), ISSN, de 17 tecknen i ett fordons identifikationsnummer, containernummer med ägarkod och kontrollsiffra samt formatet på en DOI. Kom ihåg vad validering betyder: den visar att ett värde är korrekt uppbyggt, inte att boken, fordonet eller kontot finns. Allt körs lokalt i din webbläsare, så inte ens känsliga värden lämnar din enhet.
ISO 8583 is the message format behind card payments: every authorization, purchase, reversal and network test between a terminal, an acquirer and an issuer is one ISO 8583 message. A message starts with a four-digit message type indicator (MTI) whose digits give the edition (0 = 1987, 1 = 1993, 2 = 2003), the class (authorization, financial, reversal, network management…), the function (request, response, advice) and who sent it. A bitmap of 64 or 128 bits follows, and each bit that is set says that the matching data element (DE) is present, such as DE 2 for the card number, DE 3 for the processing code, DE 4 for the amount, DE 11 for the trace number or DE 39 for the response code. Paste a message either as the text most documentation shows (MTI, hexadecimal bitmap and fields as characters) or as a hex dump of the raw bytes with BCD-packed numbers; the checker detects which one it is, strips an optional length header, lists every field with its name and flags truncated or oversized fields, bad length indicators, leftover data, impossible dates and times and unknown currency or country codes. It follows the 1987 data element table, so messages that use 1993 or 2003 layouts, private fields with their own sub-structure or a tertiary bitmap may be reported as invalid even though they are valid on your network.
Beyond identifiers, the validator also understands a few banking and payment codes. A creditor reference (ISO 11649) starts with RF and two check digits and is verified with the same mod-97 rule as an IBAN, so a mistyped payment reference is caught before it reaches the bank. A CFI code (ISO 10962) is six letters that classify a financial instrument — the first letter is the category (E for equities, D for debt, F for futures…) — and a merchant category code (ISO 18245) is the four-digit number that tells the card network what kind of business a merchant runs; both are never guessed automatically because any six letters or four digits could be one, so pick the standard from the list. Track data (ISO/IEC 7813) is what a magnetic stripe stores: card number, expiry, a three-digit service code and discretionary data, checked with the Luhn rule and a real month. The reference tables under the validator list every DE 39 response code, every ISO 8583 data element and the common merchant category codes.
Two further message formats are checked as a whole rather than line by line. A SWIFT FIN message (ISO 15022 syntax) has up to five blocks — basic header, application header with the message type and receiving BIC, user header, the text in block 4 and a trailer — and block 4 is a list of :tag: fields; the validator checks the header BICs, the mandatory fields of an MT103 (customer credit transfer), an MT202 (institution transfer) and the n99 free-format messages, and the format of the common tags such as :32A: (date, currency, amount with a decimal comma), :23B:, :71A:, :20: and the BIC-bearing party fields. An ISO 20022 message is XML whose namespace names the message (for example pain.001.001.09 or pacs.008.001.08); the validator checks that the XML is well formed, the namespace and business element match, the group header is complete, the number of transactions and control sum agree with the content, and every IBAN, BIC, currency and amount is valid. It does not replace validation against the official XSD, so use your bank's schema for the final check.
Vanliga frågor
Skickas värdet jag klistrar in någonstans?
Nej. Varje kontroll körs i din webbläsare med referenslistorna som finns inbyggda på sidan. Inget du klistrar in laddas upp eller lagras, inte ens i lokal lagring, så du kan tryggt kontrollera värden som du inte skulle lägga ut på nätet.
Betyder "giltigt" att kontot, boken eller kortet verkligen finns?
Nej. Valideringen kontrollerar bara formatet och kontrollsiffrorna. Ett giltigt IBAN har rätt längd, struktur och kontrollsiffror, men det bevisar inte att kontot finns. På samma sätt är ett giltigt ISBN eller DOI korrekt uppbyggt, inte nödvändigtvis registrerat.
Vilka standarder kan jag kontrollera?
ISO 8601 (datum, tider, varaktigheter, intervall), ISO 3166-1 (länder), ISO 4217 (valutor), ISO 639 (språk och språktaggar), ISO 13616 (IBAN), ISO 9362 (BIC), ISO 6166 (ISIN), ISO 17442 (LEI), ISO/IEC 7812 (betalkortsnummer), ISO 2108 (ISBN), ISO 3297 (ISSN), ISO 3779 (VIN), ISO 6346 (containernummer) och ISO 26324 (DOI).
Varför matchar ett värde två standarder?
Vissa korta koder är giltiga i mer än en lista. ID är både Indonesien (ISO 3166-1) och indonesiska (ISO 639-1), och 840 är både USA och US-dollar. Verktyget visar alla standarder som värdet uppfyller.
Kan jag kontrollera många värden samtidigt?
Ja. Klistra in ett värde per rad, upp till 5 000 rader, så identifierar verktyget standarden för varje värde. Filtrera på giltiga eller ogiltiga, kopiera de giltiga eller ladda ner resultatet som en CSV-fil.
How do I check an ISO 8583 message?
Paste the whole message on one line. Two layouts are understood: text (a four-digit MTI, a 16- or 32-character hexadecimal bitmap, then the fields as characters, with LL/LLL length digits for variable fields) and a hex dump of the raw bytes (BCD MTI, binary bitmap, BCD numbers). A two-byte or four-digit length header in front is detected and skipped. The result shows the MTI meaning, the bitmap and each data element, or the first problem found. Fields follow the ISO 8583:1987 table; custom formats of your network may differ.
