There's some errors in the above documents and the data is several years out of date.
Local Access
There is an error in the following text:
In the UK, local subscriber numbers can be 5, 6, 7, or 8
digits long, which depends on the area code. The UKNP contains
four route patterns that overlap, for local access.
The text should read as follows:
In the UK, local subscriber numbers can be 4, 5, 6, 7, or 8
digits long, which depends on the area code. The UKNP contains
five route patterns that overlap, for local access.
Add "4,". Change "four" to "five".
There is an item missing from the table:
| Number | Route Pattern |
|---|
| LOCAL-5-DIGIT | [2-9]XXXX |
| LOCAL-6-DIGIT | [2-9]XXXXX |
| LOCAL-7-DIGIT | [2-9]XXXXXX |
| LOCAL-8-DIGIT | [2-9]XXXXXXX |
Add the extra line at the beginning of the table as follows:
| Number | Route Pattern |
|---|
| LOCAL-4-DIGIT | [2-3]XXX |
| LOCAL-5-DIGIT | [2-9]XXXX |
| LOCAL-6-DIGIT | [2-9]XXXXX |
| LOCAL-7-DIGIT | [2-9]XXXXXX |
| LOCAL-8-DIGIT | [2-9]XXXXXXX |
Add the new text "LOCAL-4-DIGIT [2-3]XXX" to the beginning of the table.
In the details after this text:
"For example, a gateway in a 2-digit area code with 8-digit subscribers has this filter:"
there is an error in the example code:
(LOCAL-5-DIGIT DOES-NOT-EXIST AND
LOCAL-6-DIGIT DOES-NOT-EXIST AND
LOCAL-7-DIGIT DOES-NOT-EXIST)
The text should read as detailed below:
(LOCAL-4-DIGIT DOES-NOT-EXIST AND
LOCAL-5-DIGIT DOES-NOT-EXIST AND
LOCAL-6-DIGIT DOES-NOT-EXIST AND
LOCAL-7-DIGIT DOES-NOT-EXIST)
Add "LOCAL-4-DIGIT DOES-NOT-EXIST AND" to the beginning of the example.
Extended National Toll Bypass
There are two errors in the following text:
For example, calls from Reading (118) to Nettlebed (1491),
Maidenhead (1628), Ascot (1276), Bracknell (1344), Aldershot (1252),
Basingstoke (1256) and Newbury (1635) are charged at the local rate.
These two area codes changed name in 2003:
- 01491: Nettlebed changed name to Henley-on-Thames.
- 01276: Ascot changed name to Camberley.
The text should read as follows:
For example, calls from Reading (118) to Henley-on-Thames (1491),
Maidenhead (1628), Camberley (1276), Bracknell (1344), Aldershot (1252),
Basingstoke (1256) and Newbury (1635) are charged at the local rate.
Correct the names for these two area codes.
The following text is incomplete:
The OR statements appear when you add a new Clause to the filter.
See Appendix D - Five-digit Subscriber Numbers for lists of area
codes with 5-digit subscribers.
The corrected text should read as follows:
The OR statements appear when you add a new Clause to the filter.
See Appendix D - Five-digit Subscriber Numbers for lists of area
codes with 5-digit subscribers and Appendix E - Four-digit
Subscriber Numbers for lists of area codes with 4-digit subscribers.
Correct the text.
Appendix A - UK PSTN Numbering Overview
The following text is incomplete:
The UK PSTN does not have a uniform structure like the NANP.
Area codes can be 2, 3, 4 or 5 digits; subscriber numbers can
be 5, 6, 7, or 8 digits; and service codes can be 3, 4, 5, or
6 digits. National numbers can be 10 or 11 digits (including
the leading 0).
The corrected text should read as follows:
The UK PSTN does not have a uniform structure like the NANP.
Area codes can be 2, 3, 4 or 5 digits; subscriber numbers can
be 4, 5, 6, 7 or 8 digits; and service codes can be 3, 4, 5, or
6 digits. National numbers can be 10 or 11 digits (including
the leading 0) and there are two 8 digit numbers (0800 1111 and
0845 4647).
Add "4,". Add wording about the two 0800 and 0845 special cases.
In the following text:
"These are the rules for geographic numbers:"
there are some minor changes to make towards the end of this list:
2-digit area codes have 8-digit subscribers.
3-digit area codes have 7-digit subscribers.
4-digit area codes have 6-digit subscribers.
Some 4-digit area codes have both 5- and 6-digit subscribers.
5-digit area codes have 5-digit subscribers.
Some 5-digit area codes overlap with 4-digit area codes.
The corrected text reads as follows:
2-digit area codes have 8-digit subscribers.
3-digit area codes have 7-digit subscribers.
4-digit area codes have 6-digit subscribers.
Some 4-digit area codes have both 5- and 6-digit subscribers.
5-digit area codes have 5-digit subscribers.
One 5-digit area code has both 4- and 5-digit subscribers.
All 5-digit code areas overlap with 4-digit area codes.
The wording is changed in one rule and there is an additional rule.

Add this extra number range.
Appendix B - Filter Categories
There is one example missing from the following data:
| Category | Numbers* | Example |
|---|
AREA-CODE | 2, 3, 4, or 5 digits | 20, 161, 1208

Add the additional number ranges.
Note: In the other Cisco UK Numbering Plan document, these are referred to as: LOCALRATE-ACCESS, LOCALRATE-SUBSCRIBER, NATIONALRATE-ACCESS and NATIONALRATE-SUBSCRIBER with only one hyphen.
Note: It is now illegal in the UK to use the terms "local rate" and "national rate" to describe these numbers in advertising as the price of calling them is higher than calling a normal geographic number.
These new number ranges, allocated in 2008, are missing from the table:
| Category | Numbers* | Example |
|---|
| UK-WIDE-ACCESS | 30X, 33X, 34X, 37X

4-digit Area Codes with Mixed 5-digit and 6-digit Subscribers
The following number ranges have changed since 2003 and should be DELETED from the table:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| Forfar | 1307 | 8[2-4]XXX | DELETE THESE
TWO ENTRIES |
| Kircudbright | 1557 | 50XXX |
These area codes were upgraded to use only 6-digit subscriber numbers at least several years ago.
The following number ranges were mis-classified by Ofcom for many years and should be DELETED from the table:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| Wigton | 1697 | 7[23]XXX | DELETE THIS ENTRY |
This entry should show the 4-digit subscriber numbers found in the 016977 Brampton area code.
This data therefore belongs in a different table and in a different format: e.g. "16977 [23]XXX". See the final item.
The following number ranges have changed since 2003:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| Buxton | 1298 | 2[2-7]XXX | 7[0-47-9]XXX | 8[3-5]XXX |
The correct data is as follows:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| Buxton | 1298 | 2[2-8]XXX | 7[0-47-9]XXX | 8[3-5]XXX |
The part "[2-7]" changes to "[2-8]".
The following number ranges have changed since 2003:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| Alton | 1420 | 2[23]XXX | 8[02-9]XXX |
The correct data is as follows:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| Alton | 1420 | 2[23]XXX | 8XXXX |
The part "[02-9]" changes to "X".
The following number ranges have changed since 2003:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| St. Austell | 1726 | 6[13-7]XXX | 7[0-7]XXX |
The correct data is as follows:
| Location | Area Codes | 5-digit Subscriber Number Ranges |
|---|
| St. Austell | 1726 | 6[13-9]XXX | 7[0-7]XXX |
The part "[13-7]" changes to "[13-9]".
The following number range is missing from the table:
| Location | Area Code | 5-digit Subscriber Number Ranges |
|---|
| Penrith | 1768 | 88[2-46-8]XX |
The above number range needs to be added to the table.
The following area codes changed name in 2003:
- 01276: Ascot changed name to Camberley.
- 01461: Annan changed name to Gretna.
- 01488: Great Shefford changed name to Hungerford.
- 01562: Stourbridge changed name to Kidderminster.
- 01744: Rainford changed name to St Helens.
- 01963: Templecombe changed name to Wincanton.
Correct the data for these number ranges.
There's a spelling mistake in the table:
- 01557: Kircudbright should be Kirkcudbright.
Correct the spelling for this area.
A new section is needed, listing the details of 4-digit subscriber numbers:
Appendix E - Four-digit Subscriber Numbers
5-digit Area Codes with Mixed 4-digit and 5-digit Subscribers
Numbers beginning either 0169772 and 0169773 are in a 5-digit code area and have a 4-digit subscriber number:
A new table is needed as follows:
| Location | Area Code | 4-digit Subscriber Number Ranges |
|---|
| Brampton | 16977 | [23]XXX |
Add a new table to show the data for this number range.
