What is an STD used for?
I'm guessing that you mean STD = Subscriber Trunk Dialling (telephone area code) rather than STD = Sexually Transmitted Disease. STD code is another term used in some country for telephone area codes. The purpose of a telephone area code is to group telephone numbers by geographic area. In many cases, at least some calls to numbers with the same STD code as the caller can be dialed without the STD code, allowing shorter dialing sequences for many local calls.
What is a real telephone number?
A real telephone number is a telephone number that is live and connects to a landline or mobile device. There are different telephone numbers available that people don't recognise or insider not correct, this relates especially to non geographic numbers such as numbers like 0870, 0844 or when you need to dial the full area dialling code (STD) although the number should not need to be dialled in full. There are also false made up numbers such as on television shows when a real live telephone number cannot be displayed for obvious reasons.

What does STD code mean?
In the field of telecommunications in the UK, STD stands for 'subscriber trunk dialling' and is a hangover from the time when telephone users could 'phone straight through to a telephone controlled by another telephone exchange (prior to that, you had to ask the operator to put you through) The STD code is the first four (now five) digits of the full telephone number. The term STD is now a largely defunct term.
What is STD code number?
STD in telephony means Subscriber Truck Dialling. This term was used in Australia in telephony during the transition from operator connected trunk call (out of local exchange area) to full national dialling as we know it today. If a caller was calling by STD then they dialled the called telephone number themselves. When an STD call first connected a series of 7 rapid 1000Hz tones of 1ms duration were sent to the caller and called party to notify them the call was via STD and that there would be no operator intervention to advise them of the duration of the trunk call. If the call was connected my a manual operator, he / she would interrupt the call every three minute and advise the paid period of 3 minutes had expired, and offer another three minute paid connection time. These manual calls were charges in 3 minute increments, while STD calls were changed by the second.

What town is 225 dialling code in the UK?
No town has that dialling code as all exchanges external to your area start with a 0. There is no town that has phone numbers starting 0225 Since 1995 a 1 was inserted after the initial zero into all STD dialling codes. In 2000 some large areas were split off into STD codes starting 02... (eg London which was 01 was split into 071 (inner) and 081 (outer) which became 0171 and 0181 in 1995; then in 2000, the inner/outer digit (7/8) was added to the start of the 7 digit phone number to create an 8 digit phone number and the London STD code became 020.) The town that now uses 01225 is Bath. If that is an exchange in an area (eg 0121 225 1234 or 0161 225 1234) then it will depend upon the STD area (0121 is Birmingham, 0161 is Manchester in the given examples).
