My place has had 3 postcodes allocated. This converter worked for all three no problem. Now to see the grid references to see why it keeps moving!

Zyda, this just has more precision. So instead of AB 12345 67890 you could use AB 123 678 and loose some of the precision.

Any sign of a batch converter for Postcodes to OS Grid Refs?
By Matt on 8th October 2013
Tell me bt31 3qu, did you leave space between bt31 and 3qu? If you did then it won't show your reference. You must enter it as bt313qu!!! DOH
By Grid master on 7th October 2013
completely useless, it didn't find my grid reference or does bt31 3qu not exist
