| Entering dashes in account number | The portal says it does not recognize special characters. | Enter account number without dashes. |
| Entering both account and address | The portal says to enter either, not both. | Search one way at a time. |
| Using street type in address search | The portal says not to enter Rd, St, Ln, etc. | Enter house number and street name only. |
