What are the rules for using numerals in addresses?

The rules for using numerals in addresses vary depending on the specific style guide or formatting guidelines being followed. However, there are some general rules that are commonly followed:

1. Use numerals for house numbers: When indicating the specific house number in an address, it is generally preferred to use numerals rather than spelling out the number. For example, "123 Main Street" is preferred over "One hundred twenty-three Main Street."

2. Use numerals for street numbers: Similar to house numbers, street numbers are typically written using numerals. For instance, "5th Avenue" is preferred over "Fifth Avenue."

3. Use numerals for apartment or unit numbers: If an address includes an apartment or unit number, it is usually written using numerals. For example, "Apt. 10" or "Unit 5B."

4. Use numerals for ZIP codes: ZIP codes, which are used to identify specific geographic areas, are always written using numerals. For instance, "90210" is the numerical representation of the famous ZIP code for Beverly Hills.

5. Use numerals for building or floor numbers: If an address includes a building or floor number, it is typically written using numerals. For example, "Building 7" or "Floor 3."

6. Use numerals for numbered streets: When referring to numbered streets, such as "1st Street" or "10th Avenue," it is customary to use numerals rather than spelling out the number.

7. Use numerals for fractions: If an address includes a fraction, such as "1/2 Main Street," it is generally written using numerals.

It is important to note that these rules may vary depending on the specific style guide or formatting guidelines being followed. Therefore, it is always advisable to consult the relevant guidelines for accurate and consistent usage of numerals in addresses.
