BRP return which address

[Hola2015]

Hi,
Many apologies if this question has been answered before. We attended our citizenship ceremony yesterday and since it is now a requirement to return the BRP card latest 5 days after receiving the certificate.

In the ceremony package given to us by the council, there is a slip inside with the following adress:

Freepost RRYX-GLYU-GXHZ
Returns Unit
P O Box 163
Bristol, BS20 1AB

While on the gov.uk website the return address is stated as:
POL Returns
PO Box 195
Bristol
BS20 1BT

My question is which of these addresses should be used to return the BRP card please?

Thanks

Either! One is a freepost address so won't cost you anything in postage. The other you have to pay for postage.
