Adding three digits to dial a toll free number

[FTLE420]

Hi all,
What would be the best way of adding a three digits code to dial a toll free number in a 81c RELEASE 4?
We have been task to add the toll free suicide hotline of 988 in the three 81c switches we have here.
Couldn't use 98 because 98 is used for something else. Looking to use 966. Any and all help would be appreciated.

Thanks
