Reasonable Address
All query addresses that have been rated Invalid should be analyzed to see if they are Reasonable.
For an address to be rated as Reasonable, it must refer to a location that exists in the real world AND be at least one of:
A small area that has at most five rooftops and is on one side of a block
An area on one side of the street that is equal to or smaller than a block
A small area that cannot be broken down any further in terms of address components
◦ The address in the result is as specific as it can be for the locale
A plaza-like feature
A residential complex that is equal to or smaller than two blocks in size
An address/postal code that defines a small area that is within eyesight:
The area should not include any visual impediments such as turns in the road or other buildings Trees are not considered visual obstruction
If in doubt between a block and within eyesight, choose the most generous of the two
Is a non-existing address a reasonable address?
No. According to the section 4 of the guideline, for an address to rated as Reasonable, it must refer to a location that exists in the real-world.
Reasonable Address

EXAMPLE
Query: Mariahilfer Straße 66-68 1070 Wien
Is the query a valid address?
Valid
✓Invalid .
Is the query a reasonable address?
✓ Reasonable
Not Reasonable
Since the query is for an address range and does not refer to a single building, as discussed earlier, this is an Invalid address. However, the address range is Reasonable because it contains fewer than 5 rooftops. A user in this area will be able to find the intended location. Official source: geoland.at

EXAMPLE
Query: Linakstraße 60 8051 Thal
Is the query a valid address?
Valid
✓Invalid
Is the query a reasonable address?
Reasonable
✓ Not Reasonable
Research shows that the number 60 does not exist on Linakstraße in Thal. This street goes up to #58. The address does not refer to a real-world location, so it is Invalid (GL-Section 3). It is Not Reasonable because it must refer to a location that exists in the real-world (GL- Section 4) Official source: geoland.at
As long as the address refers to a real-world location and it refers to a single unique location (unambiguous), then it can be considered a valid query address.
You will rate the response addresses for all query addresses you rated Valid and Invalid but Reasonable. To evaluate the quality of a response address, you must compare it to the Valid query address.
Note: While in Maps Search result addresses are rated independently, in Address Verification, you must rate response addresses in relation to the query address.
A correct response address will refer to the same unique location as the query address and be complete and well formatted. If any portion(s) of the response address are missing or incorrect, use the appropriate rating.
The response address can be:

EXAMPLE
Query: Merianstraße 7A 5020 Salzburg
Is the query a valid address?
✓ Valid
Invalid
Response address: Merian Straße 7A 5020 Salzburg
According to the official source geoland.at, correct street name is Merianstraße. There is an extra spacing in the response address. Correct rating: Correct with Formatting Issue (GL-Section 7.2.)
Incorrect

EXAMPLE
Query: Kohlsiedlung 17 6091 Götzens
Is the query a valid address?
✓ Valid
Invalid
Response address: Kohlsiedlung 15 6091 Innsbruck
Response Pin: 47.234585, 11.333423
We must rate response addresses in
relation to the query address. In the
query address, the user is looking for the
#17, but the response address returns
with the street number #15. Additionally,
according to the official source, correct
locality is Götzens. Therefore, correct
rating is ”Incorrect – Street number + Locality”. The pin drops on the rooftop of #15, because we must rate Pin also in relation to query address, Correct rating would be “Next Door” with the correct pin: 47.234577, 11.333183
