Navigate to the Carlos Celdran Tours Office

We have added the Carlos Celdran tours office into our maps, so Filipinos, balikbayans and our foreign visitors can find it.

We have two waypoints:

  • Carlos Celdran Booking office (with phone numbers on the favorites)
  • Carlos Celdran Parking (this is for the intramuros tour)

Every Filipino should get to experience this.  It is an eye opener considering what we were taught at school.

Tour Highlights

  • Spanish, Chinese, Japanese and American influences
  • What culture?
  • Chocnut
  • Why there were no Spanish women in the Philippines during the Spanish era
  • Father Damaso, the R.H. bill and the impact on the tour
  • World War 2 Bombs

Choosing Between In-Dash GPS Navigation or Portable GPS Navigation Devices

At the end of the day it all boils down to personal choice.  However, these are the things we found out while using / testing various GPS navigation devices.

Category In-Dash Portable (Stand Alone)
Acquisition Cost High

Maybe free for new cars

Map Upgrade Cost High Low
Map upgrade complexity Complex Simple in most cases
Portability 1 Car only



Multiple Cars (coding cars)

Used for walking

Device Security Difficult to steal Easy to steal
Mounting Clean / In-Dash Messy, wiring is all over the place
View Difficult, too low, really depends on vehicle it’s installed on. Configurable / Movable

Choosing a brand for GPS Navigation

Garmin is still the best brand out there, simply because there is an open source community for maps, if you can’t afford commercial ones or simply do not want to pay for it.

It has proven to be tough even in warmer climates like the Philippines.  There are cheap models you can get from Amazon, ebay or Walmart. Just get the balikbayan relatives or friends to ship it to you.  Better yet, get them from the local malls.

Writing Proper Philippine Addresses

Streets in the PhilippinesIntroduction
Since we could not find any online documentation for writing proper address information in the Philippines, we decided to create one.

In coming up with this protocol, we had to consider a number of issues, like not having specific house numbers; inconsistent conventions; poorly sourced conventional wisdom ; living in the provinces and generally not knowing your own barangay or postal code and let us not forget to add “not having visible street signs”.

So for lack any government guidance here it is.


<Unit No> < Building Name>  or  <Lot No / Block No>
<House No> <Street Name>
<Village/Subdivision>  or  <Postal Code Name>  or  <Purok Name>
<Barangay Name> < Postal Code> <City/Municipality Name>
<Province>, <Country>

The protocol starts in reverse order with the largest parcel which is the country, followed by smaller parcels city, municipality and so on, In effect drilling down to a specific location.

Some Examples

Building Based Address

Juan Dela Cruz
Unit 21 Greenbelt  Residences
37 Esperanza Street
Greenbelt, Makati 1228
Barangay San Lorenzo
Metro Manila, Philippines

Village Based Address

Juan Dela Cruz
11 Main Avenue
Merville Park Subdivision
Barangay Merville 1706 Paranaque City
Metro Manila, Philippines

Provincial Address

Juan Dela Cruz
Purok 4
Barangay Canitu-an 1610 Kalilangan
Bukidnon, Philippines

Village Based Address (Lot Block)

Juan Dela Cruz
Lot 4, Block 6
President Roxas Street
South Admiral Village
Barangay Merville 1709 Paranaque City
Metro Manila, Philippines

The Odd Balls
No one quite knows whether this is a political block or a geographical block? But it seems in the provinces purok is a way to find a person’s location.

<Postal Code Name>
The Philippine postal office attaches description(s) or name(s) to a postal code.

The conventions are confusing, it is not a barangay.  It does seem to be a village name (e.g. Merville, Greenhills) or a popular locality name (e.g. Binondo, Malate) when in metro manila, and it takes the municipality name when outside of Metro Manila.

This might be because of population size considerations however it causes location finding issues when used for large municipalities such as Davao City which carries a single postal code of 8000.  It may be that the postal office is extremely slow to react (similar to their mail services) to population changes, hence Davao with a population of more than a million is still a single postal code.

<Lot No / Block No>
This is the most annoying of all, we cannot route to a location with this information!  It is impossible to do with Navigation Software.  If we understand this correctly, this identifier is meant to be used by property developers to sell lots.

Process Ownership

If anyone from the Philippine Government reads this kindly send us an email and tell us who is supposed to be responsible for assigning addresses and postal codes?

We might even help you do this pro-bono.
