Can a mailing address be lower case not email

Yes, a mailing address can be written in all lowercase letters, but it's not a common practice. Here's why:

  1. Readability: Mailing addresses are often read quickly and scanned for errors. Using all lowercase letters can make it harder to read and understand the address, especially for older adults or those with vision impairments.
  2. Postal Service guidelines: The United States Postal Service (USPS) recommends using all capital letters for street addresses and city names, with only the first letter of the street name and the city name in lowercase. This is to ensure accurate sorting and delivery.
  3. Professionalism: In business and formal correspondence, it's common to use title case (first letter of each main word capitalized) or sentence case (first letter of the first word capitalized, with the rest of the letters in lowercase) for mailing addresses. This helps maintain a professional appearance.

That being said, if you're writing a mailing address in all lowercase letters, it's not necessarily incorrect. However, it's essential to ensure that the address is still legible and easy to read.

Here's an example of a mailing address written in all lowercase letters:

123 main street anytown, ca 12345

In this case, the address is still readable, but it's not following the traditional guidelines for writing mailing addresses.
