All SMS Central dedicated numbers are sorted into Gold, Silver and Standard categories to differentiate the "quality" of these numbers. A number rated at a higher category is easier to remember and to identify than that of a lower category.
The quality of a number is determined by:
- How many sequential digits the number has
- How many identical digits the number has
- The number of patterns in the number
The following reference chart explains the categories and provides some examples (bookmark it for future reference!);
