800 vs 888 vs 833: which prefix should you choose?
800, 888, 877, 866, 855, 844 and 833 are all toll-free prefixes that work and cost the same: the caller pays nothing, the business pays for the call. 800 is the most recognized and the scarcest; the newer prefixes have far more vanity words available and attract fewer misdials. Kall8 offers all seven at the same plan price from $14.95.

| 888 | 1996 | High | Low |
| 877 | 1998 | High | Moderate |
| 866 | 2000 | Good | Moderate |

How to choose
- If the word matters more than the prefix, take the prefix where the word is available. 1-833-PLUMBER beats 1-800-758-6237.
- If you advertise on radio or vehicles, a repeater (1-866-286-1111) in any prefix is easier to remember than a word.
- If misdials cost you money (every answered call uses minutes), avoid old 800 blocks; 833 and 844 get far fewer.
- If you want the classic look and a standard number is fine, an 800 number is still available; premium 800 patterns are priced individually.

Prefix questions
