How to make clear the difference between 0 and O?
Solution 1:
Three cases pertain: speaking, handwriting, typing.
- For speaking, say "small oh".
- Handwrite a distinct small oh.
- Use a font that produces a distinct small o, or use an inline graphic for the entire company name. If needed (for customers who use email without inline graphics capability), follow the inline graphic with the company name in parentheses (ia2o ltd.).
This answer is brought to you by personal experience.
- Take over and rename the company.
