It is a text type. There are a number of reasons why you do not use a number type. Most phone numbers in their full form start with a zero. If entered into a number field, the zero would be dropped. Number fields do not allow spaces or other characters, such as hyphens or brackets, that are often used when entering phone numbers. Although they are numbers, you never do calculations on phone numbers, like adding or multiplying or getting averages. So no numerical operations are carried out.
In Access and in databases in general each field in a database table is of a certain data type. The data type determines what type of data a field can hold. A field of the text data type can hold text, a field of the number data type can hold numbers and a field of the data/time data type can hold date and time values.Access actively checks what type of data is entered into a field and Access will disallow the entry of data into a field that doesn't conform to the field's data type. Access won't allow you to put text into a field of the Number data type, for example.So, data types are a way to restrict the entry of data into a field. Internally, the database uses different strategies for the storage and retrieval of different data types.
Some telephone numbers starts with number 0 (zero) or the country code with + marks (If you type the full number properly). For instance a number like 0094111234567 or +94111234567. If this number is stored under the "Number" data type, two things can happen. 1. Default "Number" field does not support this size of data. You have to change the Filed Size to "Double" in order to accommodate this telephone number. 2. Zero (0) in the front will get removed automatically! So To prevent these issues you can use the data type as "Text" Hope this Helps!
In a database, a number field is specifically designed to store numeric values, which can be used for mathematical operations, while a data type field encompasses a broader range of data types, including text, dates, and binary data. The number field typically supports various numeric formats, such as integers or floats, while the data type field categorizes the nature of the data being stored, defining how it can be manipulated and what operations can be performed on it. Essentially, while all number fields are a type of data type, not all data type fields are limited to numbers.
The data type of a field determines the kind of data it can contain. For example, a field with a data type of "Text" can contain letters and numbers, while a field with a data type of "Number" can only contain numerical values. The data type is set when designing the database schema.
The data type, like Number, Date, Time, Text etc.

There is a hyperlink data type. If you set a field as that data type, such as for a website, then you can type in a valid address into the field and it will be stored as a hyperlink.There is a hyperlink data type.
