Yes, they do. You can use input masks to enforce the international format of a phone number, for example.

But input masks are not the holy grail of consistent data. With input masks you can create very simple patterns that input values should adhere to. Input masks are usually used for phone numbers, bank numbers, zip codes and other code-like values that follow a strict pattern.

Validation provide more flexibility for layaing constraints on the input and with VBA you have the full capabilities of a programming language at your disposal, so this option is definitely the strongest.

What is format mask and input mask in database?

Input mask is a tool which allows the database creator to set a certain format to a certain field to show what can be entered into that particular field. You can add input masks to table fields, queries, and to form and report. Input masks provide a set format for data entry in a field by using characters and symbols. When you apply an input mask to a field, anyone who inputs data in that field must follow the specific pattern defined by the input mask. For example, if the database user enters a phone number and does not follow then input mask, In this case the input mask could be 0000 000 0000 (0 stands for number 0-9) the user will be unable to save the data until the number is entered as the input mask format. Input masks provide a large amount of data validation and prevent users from entering invalid data (such as a phone number in a date field). Input masks can also help ensure that users enter data in a consistent way. This would also improve the data that is being inputted making sure it is accurate,easier to find and understand if it's all in one the same format.
