Think of the glossary as organizing numbers by how they’re used to reach someone. Internal means dialing an inside extension, external points to outside lines, and callback designates a number saved for returning a call. These categories describe the role of the number in communication. Fax, while it uses a phone line, isn’t a type that describes how you reach someone. It’s a device or service (a fax transmission method) rather than a category for a phone number’s purpose. That’s why fax isn’t listed as a phone number type in the glossary.

Date of Loss is the date the damage happened to the vehicle. This date anchors the claim to the actual incident, which affects coverage timing, eligibility, and processing. Once this date is entered, it’s kept fixed to preserve the integrity of the claim timeline. The date a claim is opened merely marks when the claim was started, not when the incident occurred. The policy issue date relates to when the policy began, not the incident date. The date of repair is when the repair occurs, which can be after the loss date, and does not define when the loss happened.

The main idea here is using a stable, predictable indexing system to make finding information quick. Glass FAQs are arranged in numerical order, with each entry assigned a number and listed ascending. This setup lets you jump to topics by their number, and it’s easy to add new questions without reordering the whole list, which is why it’s favored for a reference resource. Organizing by account-name, by date, or in a random order would slow you down: alphabetic order depends on knowing a specific name, date order groups items by when they were asked rather than the topic, and random order offers no reliable path to a topic. Numeric sequencing provides a simple, scalable structure that supports fast lookup.

A VIN notch is a small cut in the black paint band (the frit) around the windshield that exposes the glass so the VIN can be read from outside the vehicle. This tiny opening is placed so technicians can verify the vehicle’s VIN without removing the windshield or needing a special view, which helps ensure the correct part is used and that records match accurately. The notch is the precise term used for this feature. A long opening would be a slot, a generic cutout isn’t specific enough, and a window would imply a separate visible pane rather than a small, intentional notch in the frit.
