Understanding National Change of Address in the UK
Bad addresses are costing businesses millions. More than 6 million people in the UK move each year, and outdated address lists can label a letter or bill, package or flat as undeliverable.

If too many addresses are underliverable, the mailer and its mail house can be liable for financial penalties, and suffer from poor customer communications and marketing effectiveness, lagging account receivables, and fewer sales.

Mailers or their service provider can avoid these problems by checking a mailing list against the UKs Postal Service’s National Change of Address (NCOA) database. This will verify that a recipient on a mailing list has filed a change of address notice with the Royal Mail and will note the new address as well if it is available.

Why Is NCOA Data Cleansing Important for a business?

Correcting out of date addresses using NCOALink and other methods allows mailers to meet the Royal Mail Move Update requirements for a 95-day period from the date of processing, in order to qualify for mailing discounts. Move Update is required for all marketing mail, First Class presort letters and flats, and Parcel Select Lightweight.

The costs associated with undeliverable mail can be severe. The Postal Service leverages its Intelligent Mail barcode (IMb) technology to check every single address a mailer submits in bulk for accuracy. If only 0.5 percent of addresses are faulty, failing to mirror Postal Services change of address (COA) records beyond a certain cutoff point, the mailer an be charged a fee on each bad address. The potential for thousands of pounds in penalties due to out-of-date mailing lists is very real.

What Other Methods Address The Recent-Move Challenge?

  • The Postal Service’s ACS service allows customers mailing First-Class Mail, Standard Mail, and Periodical flats or letters to receive electronic or automated address corrections using the Intelligent Mail sbarcode. This allows for the Royal Mail and other international postal services like USPS to forward mail or notify mailers of a Change of Address (COA), provided the addressee submitted a change of address request with the Postal Service.
  • Address Service Requested for UK mail means a piece of mail is forwarded, with no charge, and a separate notice of a new address is provided to the sender for a fee. This occurs for up to a year if a forwarding address is on file with the Postal Service.
  • Change Service Requested provides address correction services without forwarding or return. If undeliverable, either the new address or the reason it is undeliverable is provided to the sender.
  • Return Service Requested provides address correction services and always returns the piece.
