You are calling a toll-free number associated with a different geographical location. Be sure you are calling the toll-free number located on the Parkmobile signs or stickers which have our logo.
You are entering a number other than the zone number displayed on the Parkmobile sign or sticker.
All Parkmobile signs and stickers have our logo and include a zone number. Parkmobile zone numbers are at least three digits (numbers only) and can't start with a zero. If you enter the zone number as shown on the Parkmobile sign or sticker and you still have trouble, you should consider paying for parking another way for that session so you aren't issued a penalty. Then send an email to email@example.com so we can investigate and provide you more assistance.
