We require postcodes on ALL MAIL. Any mail without a postcode, or with a postcode that is incorrect or in the wrong place, has to be manually sorted at each process and this may cause a delay for that item. We will endeavour to deliver your post even without a postcode but we can do our job better you when you help us.
Some organisations are allocated a unique postcode to ensure the segregation of large deliveries of mail to a single address. However, a postcode will usually cover more than one address in a specific area.
The mechanised sorting equipment 'reads' the address from the bottom. It is important, therefore, that the postcode is at the end of the address on a single line by itself.
Our equipment is able to read both typed and handwritten addressing as long as it is clearly formed and not cluttered by decoration on the envelope. Poor contrast between address print and envelope colour may also make it more difficult to be 'read' by the machine. Take particular care to ensure that GY is clearly written because G is the postcode for GLASGOW while a poorly written Y can lead to your item being mis-sorted by our machines to somewhere like Guildford - GU.
No. The mechanised sorting equipment will reject incomplete postcodes as 'not registered'.
If you need assistance with coding your address database contact Customer Services on 711720.
Companies and individuals who hire Private Boxes from Guernsey Post will be aware that their Private Box has a unique postcode which is different from that of their geographic address. It is essential that the Private Box postcode is used on all communications and not the postcode associated with the box holder's physical geographic address.
If you do not know the postcode of the addressee, please use the postcode finder or telephone Customer Services on 711720 for local enquiries. For UK postcodes please telephone Royal Mail on 0906 302 1222 (from 8am-6pm Monday to Friday (calls cost 50p per minute, to a maximum of £5) or call 08457 111 222 6pm-8pm Monday to Friday, 9am-5:30pm on Saturday and 9am-2pm on Sunday (calls charged at the UK rate).
When sending mail to international destinations, please check individual countries for their addressing standards and ensure that your details are on the outside of the reverse of the item. There are special requirements for some destinations and some articles. Details are available at all Guernsey Post branches and from Customer Services on 711720.
It is recommended that all postal items display the complete name and address of both the sender and the recipient. For some countries, e.g. Canada, non compliance will result in access being denied. See our undeliverable mail policy for information on external return addresses.
Complete and legible customs declarations - along with required import documentation - must be provided to specifically identify the contents of any package leaving the Bailiwick of Guernsey and specifically when sending Special Delivery items for working next day guaranteed delivery. General descriptions such as 'gift' or 'present' are not acceptable.
