How to read a number

+34612345678

+34Country code
Spain.
6Mobile prefix
Spain has no trunk prefix — the number is just 9 digits, dialled as is. Mobile numbers start with 6 or 7.
12345678Remaining 8 digits
Subscriber number. The CNMC allocates numbers in blocks of 1,000,000 or 100,000; its lookup page shows which operator currently holds a number.

Domestic format: 612 345 678 — 9 digits, no leading 0. Because numbers can be ported, a range only shows who originally issued it.

SIM cards & keeping a number

Spanish prepaid SIMs must be registered: Ley 25/2007 (from 8 Nov 2007) requires operators to keep a register of each buyer’s name, nationality and ID number (DNI, NIE or passport). Foreigners can use a passport.

Lebara is the usual keep-number choice. Note that its terms count 90 days from the last top-up, not “any balance change”: spending credit may not count, and promotional or free top-ups don’t. If you might forget, use the official “keep my number” service at €2 a month.

Lebara Spain

Number-keeping SIM
Network
A MásOrange group brand (per the site footer); third parties say its network is moving from Yoigo to Orange
Price
Official: free SIM + plan; “Todo Incluido” plans from €7 / 28 days
Keeping the number
Lebara prepaid terms 6.1: 90 days after the last top-up (promotional or free top-ups excluded), outgoing services are blocked — only free incoming calls and SMS still work. Top up within 15 days to restore; otherwise the line is permanently cancelled (non-promotional credit refundable on request). Help centre: after more than 4 months without a top-up the number has expired and can’t be restored. Or use “keep my number”: text CONSERVA to 22333 (or ask support), €2 a month, auto-renews every 31 days; text NOCONSERVAR to 22333 to cancel
ID check
Registered under Ley 25/2007: name, nationality, ID number (DNI, NIE or passport). The online eSIM requires a two-step ID check with a passport or European ID (including biometrics) and can only be activated inside Spain
SMS & calls
A normal Spanish number. Official roaming rates (from 3 Mar 2025): China is voice/SMS zone 3 — sending SMS €1.50, calls €2 set-up + €3/min, data €25/GB. The price list only covers outgoing SMS; no price is listed for receiving. You must first make a call, send an SMS or use data in Spain before it works abroad

Pros

  • Official €2/month keep-number service
  • Foreigners can register with a passport

Watch out

  • Counts top-ups, not usage — cancelled after 90 + 15 days
  • eSIM can only be activated inside Spain
  • SMS from China costs €1.50 each; calls are expensive
