If calling local numbers (with area code prefix 757) from the counting room dial 9+[last 7 digits]. To call other area codes dial 91+[10 digit number]
|
|
- Note, all non-JLab numbers must be dialed with an area code. When calling from a counting-house landline, dial "9" first.
- To call JLab phones from outside the lab, all 4-digit numbers must be preceded by 757-269
