asiakasnumero

Asiakasnumero is a customer number used in Finnish-language contexts to identify a person within a company’s information systems. It is a unique identifier assigned to someone who has an ongoing relationship with a company, such as a customer, subscriber, or member. The asiakasnumero is used to link customer records across products and services, to locate past purchases, invoices, service requests, and communications, and sometimes to authenticate the customer in online services. It is not the same as a national personal identity number, and it should be treated as confidential.

The format and issuance of an asiakasnumero vary by company. It can be numeric or alphanumeric, and its length depends on the organization’s systems. A customer typically receives the number when signing up, opening an account, or subscribing to services. In many cases the same number remains associated with the customer across multiple products or services offered by the company.

Where to find an asiakasnumero: it is commonly shown on invoices and account statements, welcome or registration letters, or within the customer portal. Some loyalty programs or service contracts also display the number. If the number is forgotten or lost, the customer can usually retrieve or reset it by contacting the company’s customer service or using the online portal, subject to verification procedures.

Related concepts include a customer login identifier and a general customer account, while the personal identity number (henkilötunnus) is a separate, government-issued identifier. Proper handling of asiakasnumero falls under data protection and privacy regulations to prevent unauthorized use.
