As Jim has said, the address you used is fine (except that there should be a space in the postcode BA15 2JN, but that minor discrepancy would at worst cause only a delay in delivery, not a rejection). You can check the address for yourself at www.royalmail.com. Use the post code finder. You'll need to register first. You can also confirm that this lady lived at the address recently via 192.com. She is not found on the current electoral roll but that is quite probably she's asked that her name not be included in the published version. She's also not in the current BT phone book. Sorry if this is asking the obvious, but are you sure that "insufficient address" stamp came from the Royal Mail, rather than U.S. Mail? -- Arthur
