## 1. Person names

### SCB (historic, frozen)
- SCB stopped producing name statistics from 2024 and refers to Skatteverket (Namnsök page, verified). Statistikdatabasen folder BE0001 now holds only "Äldre tabeller som inte längre uppdateras" (BE0001D newborns, BE0001G whole population).
- Whole-population xlsx (verified, downloaded): https://www.scb.se/contentassets/9fe7dbb460994c72b835163dbc491ef9/namn-med-minst-tva-barare-31-december-2022.xlsx — 13.1 MB, last-modified 2024-11-21, reference date 2022-12-31, names with >= 2 bearers, names in UPPERCASE.

| Sheet | Rows (incl. 4 header rows) | Columns |
|---|---|---|
| Efternamn | 411,802 | Efternamn, Antal bärare |
| Förnamn kvinnor | 91,247 | Förnamn, Antal bärare |
| Förnamn män | 79,128 | Förnamn, Antal bärare |
| Tilltalsnamn kvinnor | 57,785 | Tilltalsnamn, Antal bärare, Medelålder (only where >= 10 bearers, else "-") |
| Tilltalsnamn män | 49,404 | same |

- Gender split: a name appearing in both kvinnor/män sheets gives P(female) = count_k / (count_k + count_m).
- Middle names: "Förnamn" = every given name a person carries; "Tilltalsnamn" = the one used. Förnamn-minus-tilltalsnamn frequency approximates middle-name usage. Legal "mellannamn" (a second surname) is a different concept, no longer grantable under namnlagen 2016:1013 (not verified this session).
- Junk rows to filter: single letters ("A"), initials ("A-C", "K C", "JR"), "A:SON".
- Legacy PxWeb tables (folder BE0001G, verified via web UI): BE0001T06AR, BE0001TNamn10 (tilltalsnamn >= 10 bearers 1999–2020), BE0001T100, BE0001T08AR, BE0001T07AR, BE0001FNamn10 (förnamn >= 10 bearers), BE0001F100, BE0001T03Ar (efternamn top), BE0001ENamn10 (efternamn >= 10 bearers 1999–2020). PxWebApi v1 (`api.scb.se/OV0104/v1/doris/sv/ssd/START/BE/BE0001/BE0001G/...`) returns HTTP 400 and PxWebApi 2 (`/v2beta/api/v2/tables/BE0001T06AR`) returns "Non-existent table" — these tables are web-UI only now (verified). Use the xlsx.
- Licence: SCB terms page (verified): "Statistik och geodata som SCB tillgängliggör som öppna data i statistikdatabasen och i vår geodataplattform har licensen Creative commons 0 1.0 Universal, CC0" and "Om du använder eller sprider statistik från scb.se ska dock som källa alltid SCB anges". The xlsx sits on scb.se, not in statistikdatabasen — flag; treat as CC0 + "Källa: SCB".

### Skatteverket (current)
- Namn på nyfödda (2021+), annual: DCAT https://skatteverket.entryscape.net/store/26/metadata/416; CSV `fbf_namn_nyfodda.csv` https://skatteverket.entryscape.net/store/26/resource/417; JSON API https://skatteverket.entryscape.net/rowstore/dataset/da2556d0-c717-45e8-a1d8-3320161d3a7d/json?_limit=100&_offset=0 (47,529 rows, verified). Columns: rangordning, kön (Kvinna/Man), fodelsear, uppdateringsdatum, namn, gruppering (Kommun/…), grupperingsvärde (e.g. ALE), antal. Names in Title case. No licence field in DCAT — flag.
- Most common surnames (> 2,000 bearers, ~500 names), 2026 text file (verified, 517 lines, format `Andersson 211808`): https://www.skatteverket.se/download/18.70685bee19c85dd5dd03b59/1775049117448/Fria_efternamn_namn_antal_textfil_2026.txt (also two PDFs). Page: https://www.skatteverket.se/privat/folkbokforing/namn/bytaefternamn/sokblanddevanligasteefternamnen.4.515a6be615c637b9aa48e09.html. Licence not stated.
- Skatteverket general open-data terms (verified): "Vår öppna data är fri att använda och kräver varken några avtal eller innebär några avgifter" under lag 2022:818; no CC licence named except on the test-number datasets (CC0).
- Skatteverket publishes no whole-population first-name list as a file; its statistikportalen "Så många har ett visst namn" is an interactive search (page 404 on fetch; unverified).

Recommendation: embed SCB 2022 xlsx-derived lists (top-N per sheet with counts) + Skatteverket 2026 surname counts for freshness.

## 2. Identifiers

### Personnummer (Folkbokföringslagen 1991:481 18 §, verified via lagen.nu)
- 10 digits: YYMMDD + födelsenummer (3 digits) + kontrollsiffra. Födelsenummer odd = male, even = female. Separator "-" ; "+" once the person turns 100. 12-digit form YYYYMMDDNNNC (no separator).
- Check digit: Luhn/mod 10 over the 9 digits YYMMDDNNN (weights 2,1,2,1,… from the left; sum digits of two-digit products; check = (10 − sum mod 10) mod 10).
- Before 1990 the first two födelsenummer digits encoded county; now random (Wikipedia, unverified officially).

### Samordningsnummer
- Same layout; day + 60 (3rd → 63); individual number random 001–999, odd male / even female; same Luhn (Skatteverket rättslig vägledning, via search excerpt; page itself blocked). Now regulated by Lag (2022:1697) om samordningsnummer (18 a § FBL repealed) — flag.
- Example from Skatteverket: man born 1970-10-03, no. 239 → 701063-2391.

### Official test numbers (Skatteverket, CC0 1.0)
- Testpersonnummer dataset: https://www.dataportal.se/sv/datasets/6_67959/testpersonnummer (DCAT: https://admin.dataportal.se/store/6/metadata/67959?recursive=dcat). "Testpersonnummer med sekelsiffror för åren 1890-2025. Nya testnummer för kommande år läggs ut i december varje år." Formats: Excel (one file), CSV (split into many period files), JSON API https://skatteverket.entryscape.net/rowstore/dataset/b4de7df7-63c0-4e7e-bb59-1f156a591763/json?_limit=100 — resultCount 43,895 (verified), one column `testpersonnummer`, 12 digits.
- Observed pattern (verified on 1890s CSV file fully and API samples at offsets 0/10000/30000/43880): every day gets two numbers, födelsenummer 238 (female) and 239 (male), through 2026-12-31; 1890s use 980/981 (plus a few 982/983/936). All Luhn-valid. Skatteverket blocks these from ever being assigned.
- Testsamordningsnummer: DCAT https://skatteverket.entryscape.net/store/9/metadata/153; years 1914–2025; CSV per year; sample file 2022 (1,498 rows): days 61–91, individual numbers 238/239, Luhn-valid.
- Should a generator restrict to these? Skatteverket does not mandate it, but only these are guaranteed never to collide with a real person; any other Luhn-valid number may be real. Recommended: default to the official series (date + 238/239, or 980/981 for 1890s) and embed nothing but the rule (~530 kB if the full list were embedded). Flag: the 238/239 rule was sampled, not exhaustively verified for every year.
- Common practice elsewhere (Faker etc.): random date + random 3 digits + Luhn — valid but collision-prone.

### Organisationsnummer
- 10 digits NNNNNN-NNNN, last = Luhn over first 9 (same algorithm as personnummer). Digits 3–4 ("month") are always >= 20, distinguishing from personnummer (Wikipedia; not found on an official page — flag).
- First digit (gruppnummer), Bolagsverket page (verified): 5 = aktiebolag, filialer, banker, försäkringsbolag, europabolag; 9 = handelsbolag, kommanditbolag; 7 or 8 = bostadsrättsföreningar, ekonomiska föreningar, näringsdrivande ideella föreningar etc.; 2 or 8 = trossamfund; 20… = state agencies (Bolagsverket itself 202100-5489); 3 = foreign companies. Wikipedia adds: 1 = dödsbon, 2 = stat/region/kommun, 6 = samfällighetsföreningar, 8 = ideella föreningar/stiftelser. Enskild firma = owner's personnummer.
- VAT number (Skatteverket, verified): "SE" + 12 digits = organisationsnummer (10) + "01" ("De två sista siffrorna är alltid 01"). Written SE556047352101.

### Bankgiro / Plusgiro (Bankgirot "10-modul" PDF 2016-12-01, verified)
- Bankgironummer: 7 or 8 digits, last digit mod-10 (Luhn) check; printed 991-2346 (7) / 5555-5551 (8), i.e. hyphen before the last four digits. 90-konton (charity) 900-000x…904-999x, always 7 digits (Wikipedia).
- Plusgironummer: 2–8 digits, last digit Luhn (Wikipedia/samlogic; not from an official Nordea page — flag). Printed with hyphen before check digit, e.g. "12 34 56-7" (convention, unverified).

### Clearing numbers / bank accounts
- Bankinfrastruktur i Sverige AB CSV (verified, 57 rows, 40 actors): https://www.bankinfrastruktur.se/media/1melztro/tabell-over-clearingnummer-250305.csv (also `/media/sqfjsvkp/clearingnummertabell-for-nedladdning.csv`, 63 rows, newer, includes Zimpler 2130-2139). Columns: `Clearingnummer;Aktör;BIC;IBAN ID;Konto-typ;Metod IBAN konvertering`. Semicolon, UTF-8 BOM. Page: https://www.bankinfrastruktur.se/framtidens-betalningsinfrastruktur/iban-och-svenskt-nationellt-kontonummer. No licence; disclaimer "garanterar inte att publicerade uppgifter är korrekta".
- Key ranges: Nordea 1100–1199, 1400–2099, 3000–3399, 3410–3999, 4000–4999 (3300 and 3782 = personkonto); Danske 1200–1399, 2400–2499; SEB 5000–5999, 9120–9124, 9130–9149; Handelsbanken 6000–6999; Swedbank 7000–7999 (4-digit) and 8000–8999 (5-digit clearing with own check digit); Länsförsäkringar 3400–3409, 9020–9029, 9060–9069; Skandiabanken 9150–9169; ICA 9270–9279; Avanza 9550–9569; Nordnet 9100–9109; Klarna 9780–9789.
- Bankgirot "Bankernas kontonummer" 2024-02-22 (verified text): Typ 1 = 4-digit clearing + 7-digit account (11 digits) with mod-11 check, weights 1,10,9,…,1; comment 1 = weigh clearing minus first digit + 7 digits; comment 2 = whole clearing + 7 digits. Typ 2 = clearing not part of the account: Handelsbanken 9-digit account mod-11 (comment 2); Swedbank 8000–8999 up to 10 digits mod-10 (comment 3); Danske 9180–9189, Nordea personkonto 3300/3782, Sparbanken Syd 9570–9579 10 digits mod-10 (comment 1).
- IBAN SE (Bankinfrastruktur page, verified): 24 chars = "SE" + 2 check digits + 3-digit IBAN ID (from CSV column, e.g. Nordea 300, SEB 500, Handelsbanken 600, Swedbank 800, Danske 120, LF 902) + 17-digit account (zero-padded; clearing included/excluded per "Metod IBAN konvertering" 1–3).

## 3. Phone

- Source: PTS "The Swedish numbering plan for telephony according to ITU-T E.164", 2024-01-08 (verified, text extracted): https://pts.se/globalassets/globala-block/nummertillstand/the-swedish-numbering-plan-for-telephony-according-to-itu---2024-01-08.pdf. Swedish "nrplansammanstallning-2026-02-04.pdf" and https://nummer.pts.se/NbrPlanSearch are behind a Radware bot check (both curl and Playwright blocked). No licence stated by PTS anywhere found; pts.se says contact pts@pts.se for data.
- 264 geographic area codes (PDF text yields 263 "Area code for" rows; one likely split across a page break — flag). Area code = trunk "0" + NDC of 1–3 digits (08 Stockholm, 031 Göteborg, 040 Malmö, 0480 Kalmar). Geographic N(S)N (NDC + subscriber) max 9 digits, min 7 (2-digit NDC) or 8 (3-digit NDC); Stockholm min 7. Each row in the PDF gives NDC, max/min length, "Area code for <name>", so a `{ndc, name}` list can be built from it.
- Mobile: NDC 70, 72, 73, 76, 79 — N(S)N exactly 9 digits, i.e. 07X-XXX XX XX (10 digits with trunk 0). Others: 71 mobile broadband/M2M (13 digits), 74 paging, 75 personal numbering, 77 shared cost, 20 freephone, 10 location-independent (10 AXX XX XX, A=1–8), 378 M2M fixed (10 digits).
- Formatting (Språkrådet/Isof frågelådan, via search excerpts): hyphen after area code, subscriber digits grouped 2–3 from the left: `08-668 01 50`, `031-123 45 67`, `0480-123 45`, `070-123 45 67` (also `0701-23 45 67` accepted). International: `+46 70 123 45 67` (drop trunk 0).
- Wikipedia "Lista över riktnummer i Sverige" cites the same PTS document (CC BY-SA — do not copy).

## 4. Company

- Legal forms + suffixes (Bolagsverket, lag 2018:1653 om företagsnamn): aktiebolag must contain "aktiebolag" or "AB" (verified); public companies add "(publ)"; handelsbolag "HB" / "handelsbolag", kommanditbolag "KB" / "kommanditbolag", ekonomisk förening "ekonomisk förening" / "ek. för.", enskild firma no suffix — statutory wording for HB/KB/ek.för. not verified on the fetched page (flag).
