Which city 0448 STD code

Answer 1

You need to specify in which country, since several countries refer to telephone area codes as "STD Codes." See the related questions below.

In India, 044 is the STD code (telephone area code) for Chennai, Tamil Nadu, formerly known as Madras. In international format, it is +91 44.

In Pakistan, 044 is the STD code (telephone area code) for Okara, Punjab. In international format, it is +92 44.

In the UK, 0448 or 044 is an invalid code.

Other countries may have domestic telephone area codes like 0448.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
