Where is that Grid Reference?

If you want to know where a particular grid reference is then enter it in the box below. A new web browser window will be opened and the http://www.streetmap.co.uk/ web site will display a map of the area with the Grid Reference marked by an arrow.

National Grid References may be entered as described below.

The National Grid reference System

The country is divided into a set of 100Km squares, each square is given a two character reference. The grid lines that form the National Grid are at 1 Km intervals. To give a unique reference defining the position of a point to within 100 metres requires a two digit area number and a six digit reference.

For instance if you look at an Ordnance Survey map of the Peak District the area code for most of the map is SK. The reference of

• Matlock railway station would be 295602, the full reference being SK295602
• Winster would be 240605, the full reference being SK240605

See the legend on your maps for a description of how to define Grid References. 

The above input panel can be used in two ways. For areas within Derbyshire that are in the area code SK a 6 character Grid Reference can be used. For other areas an eight character code can be used. 

• 6 character reference - enter the code number as defined above, e.g. 240605 for the village of Winster
• 8 character reference - to cover areas outside of the SK area you must add a digit to the start of each part of the code.

You will find these numbers by looking at the corner of your map.

For instance

• Winster's 6 digit code is 240605, to obtain the 8 character code look in the corner of the map. The digit 4 is added to the the start of 240 and the digit 3 in front of of 605 giving a reference of 42403605.
• Areas of the Peak District that fall into the SJ area require the use of an 8 character reference. For instance SJ950584 would become 39503594. Add a 3 before each 3 digit code.
• Snowdon. We can use the 8 character code 26093543 to display a map of the summit of Snowdon.
