They have a layout of the MRZ with two rows of 36 characters each, similar to the TD3 format, but with 31 characters for the name, 7 for the personal number and one less check digit.

This is due to a combination of the official Spanish translation of 9303 using "nacionalidad" rather than "ciudadania" to reflect the English original of citizenship - notable in part 3 section 7.1 which specifically addresses this potential error. In October 2023, the high level technical team of <a href="https://www.nacionalidad.uy/downloads/Flimsy_TAG4_Uruguay.pdf">TAG/TRIPS4</a> addressed the Uruguay case and it is proposed the translation is adjusted and the update is communicated to Uruguayan authorities. Uruguayan authorities have committed to reviewing their policy on the understanding citizenship should be used, which overcomes the challenge of domestic definitions of <i>nationality</i> currently differing from <i>citizenship</i>. </p> <h3>Checksum calculation</h3> <p>The check digit calculation is as follows: each position is assigned a value; for the digits 0 to 9 this is the value of the digits, for the letters A to Z this is 10 to 35, for the filler < this is 0. The value of each position is then multiplied by its weight; the weight of the first position is 7, of the second it is 3, and of the third it is 1, and after that the weights repeat 7, 3, 1, and so on. All values are added together and the remainder of the final value divided by 10 is the check digit. </p> <h3>Names</h3> <p>Due to technical limits, characters inside the Machine Readable Zone (MRZ) need to be restricted to the 10 <a href="/facts/Arabic_numerals/LryNhh26">Arabic numerals</a>, the 26 capital Latin letters A through Z, and the filler character <. </p><p><a href="/facts/Apostrophe/Te0sg9km">Apostrophes</a> and similar punctuation marks have to be omitted, but <a href="/facts/Hyphen/2qtCxIGv">hyphens</a> and spaces should be replaced by an opening angle bracket. </p><p>Section 6 of the 9303 part 3 document specifies transliteration of letters outside the A–Z range. It recommends that diacritical marks on <a href="/facts/Latin_alphabet/pqWVHpBz">Latin</a> letters A-Z are simply omitted (ç → C, ď → D, ê → E, ñ → N etc.), but it allows the following transliterations: </p> <ul><li><a href="/facts/%25C3%2585/2R3BU1nc">å</a> → AA</li> <li><a href="/facts/%25C3%2584/2R3BU1nc">ä</a> → AE</li> <li><a href="/facts/%25C3%2590/A6hNvmCp">ð</a> → DH</li> <li><a href="/facts/IJ_(digraph)/8B1kKF8Q">ij</a> (Dutch letter; capital form: IJ, the J as part of the ligature being capitalized, too)→ IJ</li> <li><a href="/facts/%25C3%2596/41AF4mKp">ö</a> → OE</li> <li><a href="/facts/%25C3%259C/41AF4mKp">ü</a> → UE or UXX</li> <li><a href="/facts/%25C3%2591/0CEs8314">ñ</a> → NXX (allowed<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> but Spanish uses U and N for ü and ñ)</li></ul> <p>The following transliterations are mandatory: </p> <ul><li><a href="/facts/%25C3%2586/Uqctr81G">æ</a> → AE</li> <li><a href="/facts/%25C5%2592/kDUta34M">œ</a> → OE</li> <li><a href="/facts/%25C3%259F/mJ1GxYKu">ß</a> → SS</li> <li><a href="/facts/%25C3%259E/lMwcxfBc">þ</a> → TH</li></ul> <p>In Germany, Austria, Switzerland and Scandinavia it is standard to use the Å→AA, Ä or Æ→AE, Ö or Ø→OE, Ü→UE, and ß→SS mappings, so <a href="/facts/M%25C3%25BCller_(surname)/GVQm2YUn">Müller</a> becomes MUELLER, Gößmann becomes GOESSMANN, and <a href="/facts/H%25C3%25A4m%25C3%25A4l%25C3%25A4inen/wPM8BwIS">Hämäläinen</a> becomes HAEMAELAEINEN. ð, ñ and ü occur in Iceland and Spain, but they write them as D, N and U. </p><p>Austrian passports may (but do not always) contain a trilingual (in German, English, and French) explanation of the German <a href="/facts/Umlaut_(linguistics)/Bj9MqpvE">umlauts</a> and ß. </p><p>Russian visas (and Russian internal passports since 2011) have a different transliteration of Cyrillic into the machine-readable zone. As an example, the letter "ч" is usually transcribed as "ch" in Russian travel documents, however, Russian visas and internal passports use "3" in the machine-readable zone instead. Another example is "Алексей" (Cyrillic version) → "ALEKSEQ" (machine readable version in an internal document). This makes it easier to transliterate the name back to Cyrillic. </p> <h3>First and given names</h3> <p>For airline tickets, visas and more, the advice is to only use the first name written in the passport. This is a problem for people who use their second name (as defined by the order in the passport) as their main name in daily speech. It is common, for example in Scandinavia, that the second or even third name is the one defined for daily usage: for example, the actor <a href="/facts/Hugh_Laurie/2DSKudYK">Hugh Laurie</a>, whose full name is James Hugh Calum Laurie. Swedish travel agents usually book people using the first and daily name if the first one is not their main name, despite advice to use only the first name. If this is too long, the spelling in the MRZ could be used. </p><p>For people using a variant of their first name in daily speech, for example the former US president <a href="/facts/Bill_Clinton/x5mwYkVh">Bill Clinton</a> whose full name is William Jefferson Clinton, the advice is to spell their name as in the passport. </p><p>In Scandinavian legislation, a middle name is a name placed between the given name and surname, and is usually a family name. Such names are written as an extra surname in passports. People have been stranded at airports since they entered this extra family name in the "middle name" field in airline booking forms, which in English speaking tradition is a given name. </p><p><a href="/facts/Chinese_name/7j9G71pj">Chinese</a>, <a href="/facts/Japanese_name/MuvehI9K">Japanese</a>, <a href="/facts/Korean_name/m04VRK98">Korean</a> and <a href="/facts/Hungarian_name/F5RzknJj">Hungarian names</a> might pose a challenge too, since the family name is normally written first. Tickets should use given name and surname as indicated in passports. </p><p>This name issue is also an issue for post-Brexit EU women under the Brexit settled status (they have two family names, a birth and marriage name, but only the birth name was used by the passport MRZ and therefore used in the settlement application, although they have been using the married name in UK population register).<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Basic_access_control/lyeQbWz7">Basic access control</a></li> <li><a href="/facts/Card_standards/eQ5WtIo9">Card standards</a></li> <li><a href="/facts/ISO%2fIEC_14443/oUq2AL5f">ISO/IEC 14443</a> (<a href="/facts/Proximity_card/fJ3p3fd6">Proximity card</a> standard)</li> <li><a href="/facts/List_of_national_identity_card_policies_by_country/HNNcz92D">List of national identity card policies by country</a></li> <li><a href="/facts/Identity_document/YovHMC8K">Identity document</a></li> <li><a href="/facts/Identity_Cards_Act_2006/EFPXCEj8">Identity Cards Act 2006 of the United Kingdom</a></li> <li><a href="/facts/Universal_electronic_card/6FmxpPWU">Universal electronic card</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://www.highprogrammer.com/alan/numbers/mrp.html">A description of the Machine Readable Passport Zone</a></li> <li><a href="https://web.archive.org/web/20070126030848/http://mrtd.icao.int/">MRTD - Machine Readable Travel Document - Home (ICAO)</a></li> <li><a href="http://www.icao.int/publications/pages/publication.aspx?docnum=9303">ICAO Standards for e-Passports: Machine Readable Travel Documents</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"Last Week for States to Ensure Expiration of Non-Machine Readable Passports".
