Czech Mobile Number Format and Carrier Ranges

Czech numbers are 9 digits with no trunk prefix. Unlike Germany, Austria, or Poland, there is no leading 0 in domestic dialling — a number is written the same way locally and internationally, apart from the +420 country code. Mobile numbers begin with 6 or 7 (601 XXX XXX through 799 XXX XXX); numbers starting with 2 to 5 are landlines. Three network operators hold the mobile market, with a handful of MVNOs reselling on their infrastructure.

• O2 Czech Republic— the former state incumbent (Cesky Telecom, later Telefonica O2), now part of the PPF Group. O2 is the largest Czech mobile operator by subscribers and runs the network that Sazkamobil, the MVNO owned by the Sazka lottery company, resells. O2 ranges are the most widely recognised on Czech platforms.
• T-Mobile CZ— Deutsche Telekom's Czech subsidiary, the second-largest operator, and the network behind the Kaktus prepaid brand that T-Mobile launched in 2013 for younger, data-first users. T-Mobile CZ and Kaktus share the same number ranges as far as verification platforms are concerned.
• Vodafone CZ— the third operator, originally Oskar Mobil before Vodafone acquired it in 2005. Vodafone CZ took over UPC's Czech cable business in 2019 and is a full-coverage national network. Its number ranges are accepted everywhere O2 and T-Mobile ranges are.
• Number portability— Czech numbers have been portable between operators since 2006, so a prefix does not reliably identify the current carrier. Verification platforms check the +420 country code and 9-digit length, not the operator.

When entering a Czech number on a verification platform, select Czech Republic (+420) from the country dropdown and type all 9 digits — for example, 601 XXX XXX. Some forms label the country as Czechia; both names refer to the same +420 code.

Czech Services That Work with These Numbers

• Alza.cz— the largest Czech online retailer, covering electronics, household goods, and its AlzaBox parcel-locker network. Alza sends SMS codes for account registration and for AlzaBox pickup, which is why a +420 number is the main e-commerce use case for Czechia.
• Rohlik.cz— grocery delivery in Prague, Brno, and other larger cities. Rohlik verifies accounts by SMS and uses the number for courier contact on delivery.
• Bolt— ride-hailing, scooters, and Bolt Food in Prague, Brno, Ostrava, and Plzen. Bolt requires SMS verification at signup and accepts +420 numbers.
• Seznam.cz— the Czech search engine and portal that still holds a large share of local search. A Seznam account gives you Seznam Email, Mapy.cz, and Sreality.cz (property listings) under one login, and phone verification is used for account creation and recovery.
• Slevomat— the dominant Czech deals and voucher marketplace, verifying accounts by SMS.
• Zasilkovna (Packeta)— the pickup-point and Z-BOX locker network used by most Czech e-shops. Pickup codes and delivery notices are sent by SMS to the number on the order.
• Messaging — WhatsApp, Telegram, Signal
• Social media — Instagram, Facebook, Twitter/X, TikTok
• Google services — Gmail, Google Account, YouTube
• Finance— PayPal, Wise, Revolut
• Gaming and entertainment — Discord, Steam, Spotify

What a Temp +420 Number Does Not Cover: BankID

Bankovni identita (BankID) is the shared login system run by the Czech banks. It is used to sign in to government portals — the Portal obcana, the tax portal, and the ePreskripce prescription system — and it is the identity layer inside most Czech bank apps. BankID is tied to a bank account opened under in-person or video KYC, and the phone number attached to it is the one registered with the bank. A temporary +420 number cannot create a BankID identity or receive its login codes. Treat this page as covering consumer apps and marketplaces only; banking and state services need a number registered in your own name.

No. Bankovni identita (BankID) is the login layer for Czech government portals such as the Portal obcana and for most Czech bank apps. It is tied to a bank account opened with in-person or video KYC, and the phone number is registered with the bank during that process. A temporary +420 number cannot be used to create or log in to a BankID identity. Temp numbers cover consumer apps and marketplaces — Alza, Rohlik, Bolt, Seznam, Slevomat, Zasilkovna — not banking or state services.
