Using the Multibanco Network

What Multibanco actually is

Multibanco (operated by SIBS) is a single national interbank network that every Portuguese bank, savings bank and credit union belongs to. It runs ATMs, in-shop card terminals, online payment references, MB WAY mobile payments, top-ups for prepaid SIMs and tolls, and bill payments for utilities, taxes and fines. There is no equivalent in most countries: no separate Visa/Mastercard/AmEx tiers, no out-of-network ATM fees between Portuguese banks, no patchy retailer acceptance. If a payment can be made in Portugal, Multibanco usually mediates it.

Using a Portuguese card at the ATM

Any debit card from any Portuguese bank works at any Multibanco ATM with zero withdrawal fee — there is genuinely no concept of 'out of network' between domestic banks. The menu is in Portuguese by default but always offers English (and usually French, Spanish, German). Beyond cash, the same ATM lets you check balances, transfer between any Portuguese accounts, pay bills, top up phones and tolls, deposit cash, deposit cheques, and even buy concert tickets.

• Daily withdrawal limit: usually €200–€400, set per card by your bank in the app
• Per-transaction limit: €200, often allowing two consecutive withdrawals
• ATM operating hours: most are 24/7; a small number close at night in residential streets
• Using a foreign card: Visa/Mastercard works fine but your home bank may charge €2–€5 plus FX

Why US and Asian cards sometimes misbehave

Portuguese terminals are strictly chip-and-PIN with online authorization in EUR. US cards configured for magstripe fallback, signature instead of PIN, or 'dynamic currency conversion' (DCC) often get declined or charged terrible rates. A few rules avoid 90% of problems:

• Set a PIN on every card before you fly — call your US issuer if you don't have one
• Always choose to be charged in EUR, never in USD — DCC adds a 3–8% spread on top of your card's own FX
• If a terminal asks for signature, the cashier may insist on PIN regardless — switch cards rather than argue
• Apple Pay / Google Pay work essentially everywhere and bypass most magstripe issues

Payment references — Entidade + Referência + Valor

Half of Portuguese commerce moves on 'MB references': a payable bill is converted into three numbers — a 5-digit Entidade (the merchant code), a 9-digit Referência (the invoice ID) and a Valor (the amount). You go to any Multibanco ATM, choose 'Pagamentos / Serviços / Pagamentos de Serviços', enter the three numbers, and pay. Or do the same in your bank app. The biller is notified within seconds.

• Common uses: utility bills, IRS taxes, parking fines, online purchases at PT retailers, university tuition
• References usually expire in 30–90 days — pay before the deadline or request a new reference
• References are bank-agnostic — any Portuguese ATM or bank app can pay any reference
• International equivalents (SEPA Instant) are slowly arriving but MB references remain dominant

MB WAY — instant peer-to-peer and online checkout

MB WAY is the mobile-first layer on top of Multibanco. Once you link a Portuguese debit card to a Portuguese phone number inside your bank's app, you can: send money instantly to any Portuguese phone number, generate single-use virtual card numbers for online shopping (great for risky merchants), pay in shops by scanning a merchant QR code, and receive payments at small businesses without a card terminal. Almost every Portuguese person under 50 uses it — it's the country's de facto Venmo/PayPal.

What Multibanco does that PayPal can't

A few things only Multibanco does, and you'll meet them often:

• Pay your annual IRS tax bill at any ATM at midnight on the deadline
• Top up Via Verde (toll road transponder) so you don't get fined on motorways
• Buy a concert ticket from Ticketline directly at the ATM and print it on the spot
• Recharge a prepaid phone from any provider in 30 seconds
• Withdraw cash for a Portuguese friend by sending them an MB WAY 'cash code'

Common pitfalls

Three things newcomers learn the hard way.

• Foreign-issued credit cards are sometimes refused at MB-only terminals (small merchants, parking machines, kiosks). Carry a Portuguese debit card as backup
• Some ATMs in tourist zones (airport, Baixa) are run by Euronet, not Multibanco — they charge €5+ per withdrawal. Look for the blue Multibanco sticker, not the yellow Euronet one
• MB references are case-sensitive numerical, not alphanumerical — if you mistype one digit, the payment goes to a different invoice and is hell to recover
