# Instructions
2+
3+
Clean up user-entered phone numbers so that they can be sent SMS messages.
4+
5+
The **North American Numbering Plan (NANP)** is a telephone numbering system used by many countries in North America like the United States, Canada or Bermuda.
6+
All NANP-countries share the same international country code: `1`.
7+
8+
NANP numbers are ten-digit numbers consisting of a three-digit Numbering Plan Area code, commonly known as _area code_, followed by a seven-digit local number.
9+
The first three digits of the local number represent the _exchange code_, followed by the unique four-digit number which is the _subscriber number_.
10+
11+
The format is usually represented as
12+
13+
```text
14+
NXX NXX-XXXX
15+
```
16+
17+
where `N` is any digit from 2 through 9 and `X` is any digit from 0 through 9.
18+
19+
Sometimes they also have the country code (represented as `1` or `+1`) prefixed.
20+
21+
Your task is to clean up differently formatted telephone numbers by removing punctuation and the country code if present.
22+
23+
For example, the inputs
24+
25+
- `+1 (613)-995-0253`
26+
- `613-995-0253`
27+
- `1 613 995 0253`
28+
- `613.995.0253`
29+
30+
should all produce the output
31+
32+
`6139950253`
33+
34+
**Note:** As this exercise only deals with telephone numbers used in NANP-countries, only 1 is considered a valid country code.
