I want to assign unique numbers(ID - whole number) to my existing and newly created contacts.
I don't want to create a new entity for auto numbering.

No, it will not be a guaranteed unique id. If that's necessary, you can have a look at using Guid's (nl.wikipedia.org/.../Globally_unique_identifier), but if that's an option, just use the record id. Or you need to use a consecutive number and store the last value somewhere.
But will this return unique ID's? cause random function may not guarantee uniqueness
you can generate random number for the same. use below reference for plugin code

Look at one of the many out-of-the-box, open source or commercially available auto number solutions. Most that I know us at least one custom entity to track the last used number.
