Comprehensive overview of Allied Irish Banks (AIB) in Ireland: history, services, regulatory status, account opening and contact information for personal and business customers.

Allied Irish Banks (AIB) — Ireland
Allied Irish Banks (AIB) is one of Ireland's largest and longest-established banking groups, providing a broad range of financial services to personal, business and institutional customers. This article summarizes AIB's history, the types of banking it conducts, key products and services, notable specializations, its regulatory and deposit protection status, a general account opening guide, and contact channels.
Brief history and founding
AIB was formed in 1966 through the merger of several long-established Irish banks. The resulting group drew on banking operations with roots in the 19th century and became a major national bank in the Republic of Ireland. Over subsequent decades AIB expanded its retail and commercial footprint across Ireland and developed corporate and financial markets capabilities.
Like many European banks, AIB was materially affected by the global financial crisis of 2008 and the subsequent stress in property and credit markets. The bank received government support and went through a period of recapitalisation, restructuring and a return to private ownership in the 2010s and 2020s. Today it operates as a commercial banking group focused primarily on the Irish market while maintaining some international activities.
Type of bank
AIB is a universal bank that combines several types of banking activities:
- Retail banking: current accounts, savings, payments and consumer lending for individuals.
- Commercial and SME banking: lending, deposits and cash management for small and medium-sized enterprises.
- Corporate banking: tailored financing, transactional banking and advisory services for larger corporates.
- Capital markets and treasury services: market access, foreign exchange, and liquidity management for institutional clients.
AIB does not primarily position itself as a global investment bank; its core focus is domestic retail and commercial banking supported by corporate and markets capabilities.

Regulatory status and deposit protection
AIB is regulated by the Central Bank of Ireland and operates as a credit institution under Irish and EU banking law. As such, it is subject to prudential supervision, consumer protection rules and anti-money laundering regulations applicable in Ireland and the European Union.
Deposit protection in Ireland is provided through the national Deposit Guarantee Scheme (DGS), which implements the EU Deposit Guarantee Schemes Directive. Eligible deposits at a given institution are protected up to €100,000 per depositor, per institution. Certain temporary or specific deposits may be eligible for higher coverage for limited periods under the DGS rules; customers should consult the bank or the Central Bank of Ireland for details on specific cases.
How to open an account (general overview)
Opening an account with AIB typically follows standard banking procedures. While exact steps vary by product and customer type, a general overview is:
- Choose the account type: personal current account, savings account or a business account depending on needs.
- Prepare identification: valid photographic ID (passport or national ID card) and proof of address (utility bill, bank statement or similar issued within a recent period).
- Provide supporting information: for business accounts, company registration documents, proof of trading address, ownership details and relevant identification for directors and beneficial owners.
- Complete application: in-branch, online or via the mobile app where available. Some accounts and services require an in-branch visit for verification.
- Credit and risk checks: the bank may perform credit checks or due diligence before approving credit products such as overdrafts or loans.
- Receive account credentials: when approved, customers receive debit cards, online banking credentials and details on how to manage the account.
